Recommended: 3D measurement technology Which measurement technology should I use? Which device and which provider are the best choice for performing my measurement task? In the age of multimedia and information overload, it is clear that especially those suppliers who were recommended the most, are also trusted the most. Thus, every year we have our customers speak for us and have them present our measurement systems including information about applications and benefits. The latest statements are published in the new, third edition of FOCUSvariation. Common applications in different industries give an idea of where and how to use the Focus-Variation technology. One aspect that our customers very often associate us with, is reliability. This clearly reflects the standards that our company sets itself. A large emphasize is put on being a dependable and competent partner, offering 3D measurement devices that deliver reliable results. More than a mere determination of the "Ra" value is necessary in order to generate added value from a measurement. For this reason our measurement systems enable easy automation, area based measurements as well as simple and intuitive operation. Users gain traceable and repeatable results and benefit from multiple use at no additional cost. All Alicona measurement systems for quality assurance in research and production are based on these principles. This also applies to the new, quick InfiniteFocusSL system from the InfiniteFocus line. Come and see yourself how fast and simple 3D measurement can be!
Maybe you will be the next one to recommend us. Yours faithfully,

INFINITEFOCUS HOW TO MEASURE FORM AND ROUGHNESS IN ONE SYSTEM
THE SYSTEM
InfiniteFocus is an optical 3D measurement device that is universal, flexible and applicable in many industries. It combines the functionalities of a surface measurement system and a micro coordinate system in one measurement device. Even when measuring complex forms and large measurement areas, operators achieve a vertical resolution of up to 10 nm.
THE BENEFITS
Users perform high resolution measurements of even complex components with steep flanks and varying material properties. This also applies to polished components or forms with small radii and angles. Every measurement provides color information registered to the 3D data.
THE APPLICATION
Typical applications are the cutting edge measurement of drills, milling cutters etc. as well as quality assurance of micro precision components in the automotive industry, aerospace industry, medical technology or micro die casting industry. Other applications are paper and print industry, micro electronics and forensics.
THE EXPERIENCE „We use InfiniteFocus to measure micro end mills. Here, the option of full form measurement is a key benefit. In our view Alicona has no competition in this field! Also, the system is remarkably easy to use and extremely robust – from my point, InfiniteFocus is an unbreakable device.”
Frank E. Pfefferkorn, Ph.D. Associate Professor, Mechanical Engineering University of Wisconsin-Madison

WHAT MAKES INFINITEFOCUS DISTINCTIVE Form and roughness measurement with only one system Usually, when measuring roughness a surface measurement system is used whereas for dimensional accuracy or verifying tolerances a coordinate measurement system is used. InfiniteFocus offers the functionalities of both device types combined into one system. Consequently quality assurance becomes more cost-effective, is easier to execute and delivers results more efficiently.
Measure small radii and angles even across large measurement volumes More than 100 mil measurement points ensure a meticulously detailed measurement. This is how components and tolerances within the µm or sub-µm range are measured. The high measurement point density of Focus-Variation enables operators to gain a consistently high lateral and vertical resolution even across large measurement areas. Traceable measurement is also provided of small radii, angles and roughness which are often difficult to access.
Measure steep flanks In contrast to other techniques, light coming from different directions is used to positively influence a measurement. In addition, the measurement of the maximum flank angle is not restricted by the numerical aperture. Depending on the surface users measure flanks of up to approximately 90°. This is achieved via add-ons such as optional ring light or polarization to support the measurement of complex geometries.
10
alicona I InfiniteFocus USPs
A technology that measures form and roughness. A flexibility that allows almost unlimited application. A resolution that remains constant over the whole measurement range. And an ease of handling that makes InfiniteFocus a popular measurement device that is widely used.
Measure components with varying surface finishes or coating InfiniteFocus is based on an intelligent lighting technology. The patent pending SmartFlash technology allows quick and intuitive measurement of materials with varying surface characteristics or reflection patterns. Modulated light provides optimal illumination throughout the whole measurement area. Operators measure glossy, ground, rough, reflective and diffuse components.
Full form measurement with the Real3D technology Meaningful quality assurance requires area based measurements. Due to various hard and software modules, the Real3D technology enables full form measurement of components. Individual measurements from various directions are automatically reassembled for a complete 3D view. This way operators also measure complex contours and surfaces that can hardly be measured optically in the conventional way.
Measure even large and heavy components The robust technology of Focus-Variation combined with the vibration isolation frame of InfiniteFocus allows the measurement of roughness plus form on heavy and large components. The spectrum of measurable surfaces goes hand in hand with the respective weight classes up to the dcm2 range.

MEASUREMENT MODULES BASED ON FOCUS-VARIATION All measurement modules installed in InfiniteFocus provide in-depth information of the measured objects geometry´s coordinate system. In addition, a variety of form removal utilities are available for form and roughness measurement. This allows simple, accurate and repeatable surface measurement on simple and complex components. All measurement modules are designed by Alicona and are optimally tailored to each other, ensuring user friendly operation.
PROFILE-FORM MEASUREMENT Form measurement along a user defined profile Radii, angles, height steps and normal distances are measured automatically or manually. In addition, the profile-form measurement enables the verification of surface parameters such as circum-circle and in-circle plus a series of further thread parameters. Cutting edge measurement can also be performed and users measure radius, basket arch form – both “waterfall” and “trumpet” type – wedge angle and bevel lengths.
ROUGHNESS MEASUREMENT Classic profile-based measurement of Ra, Rq, Rz conforming to ISO 4287, 4288 Roughness is measured with comprehensive parameter evaluation of roughness, waviness and frequency. Statistical evaluations and the bearing ratio curve or spectral analysis are graphically visualized.

Advanced graphic visualization, including registered color information, enhances the options to characterize surfaces and a series of export functions increase user friendliness. Also complex parameters are visualized and measured from different perspectives.
AREAL SURFACE TEXTURE MEASUREMENT Surface measurement according to ISO 25178 Surface roughness, in this module, is measured area based instead of profile based. Statistics include bearing area curve, fractal dimension, autocorrelation, gradient distribution, local homogeneity and spectral distribution. A specially designed filter allows form removal to verify roughness on large measurement fields.

MEASURE FROM EVERY POSITION
The Real3D technology automatically merges individual measurements from various directions into a complete 3D data set. InfiniteFocus is not limited to a view from one perspective when performing measurement. If required, a component is measured in 3D from different perspectives. This can either be achieved manually by the operator positioning the respective part or automatically by using the appropriate hardware add-ons. In both cases the individual measurements from various positions are automatically merged into a complete 3D data set. The
"Real3D" technology allows the component's visualization from different angles plus a measurement of contour, difference and form. This way, surface parameters that are normally difficult to access are measured quickly and effortlessly. Measuring with the Real3D technology is essentially more user friendly and more accurate than it can be achieved with conventional stitching techniques on the basis of mechanical rotation or transmission

IF-EDGEMASTER HOW TO MEASURE CUTTING EDGES OPTICALLY AND REPEATABLE ALSO IN PRODUCTION
THE SYSTEM
The IF-EdgeMaster is an optical 3D measurement device to automatically measure cutting tools. Typically, the system is used to measure cutting edges regardless of type, size, material or surface finish of the tool. Users measure radii > 2µm as well as rake, wedge and clearance angle of cutting edges. Both waterfall-type and trumpet-type are precisely measured. The robust technology of Focus-Variation delivers stable and traceable measurements also in a production near environment.
THE BENEFITS
The IF-EdgeMaster delivers fully automatic measurements and stable results even with external vibration and external light. The system provides user friendly operation with high measurement speed. High vertical resolution enables chipping measurement and, in addition, traceable roughness measurements at the rake face of an edge. A patent pending illumination technology enables optimized illumination of surfaces with short exposure times, leading to fast measurements.
THE APPLICATION
Users benefit from high resolution measurements during the whole manufacturing process. The IF-EdgeMaster is used to measure the green part of a tool as well as the highly polished component in its final stage. Typically, the measurement system is used to measure inserts, drills, millers etc. Advanced visualization including registered true color information allows transparent and provable quality assurance.
THE EXPERIENCE
“In addition to the large variety of measurement possibilities, it was the user friendly operation of the system that convinced us in the first place. These characteristics combined with the high measurement accuracy make this device an ideal tool for our production!” Ulrich Weber Special Tools Construction, SIMTEK

IF-PORTABLE HOW TO MEASURE MICRO STRUCTURED SURFACES ON LARGER COMPONENTS
THE SYSTEM
The IF-Portable is an optical 3D measurement device to measure form and roughness on also larger components. The standard configuration allows the high resolution measurement of surface fields of up to (mm) 50x50x19. Typically, the system is used for near and or in production quality assurance. As an easy to handle and portable system it is a flexible measurement station which can be used wherever it is needed.
THE BENEFITS
A key feature is the integrated revolving nosepiece to change objectives and measurement resolution. This increases measurement precision as each objective is pre-calibrated, avoiding error-prone readjustment or recalibration processes. Also, easy automation of measurements increases process reliability, production efficiency and usability.
THE APPLICATIONS
A large vertical scanning range enables the measurement of various geometry types and forms. Amongst others, a key application is platen inspection in print industry. Further fields of use are the measurement of turbine or rotor blades, steel and body type surfaces. Users achieve traceable measurements in high repeatability.

RELIABLE ROUGHNESS MEASUREMENT MEANS TRACEABLE ROUGHNESS MEASUREMENT
Based on the Focus-Variation technology, InfiniteFocus offers a high measurement system capability for measuring surface roughness. Roughness is measured profile based according to ISO 4287/88 and area based according to ISO 25178. Due to unique technology and system specific characteristics, operators perform repeatable and traceable roughness measurements down to 0.05 µm. A high vertical and lateral resolution enables measurements of components with low roughness but also of highly textured surfaces. This measurement performance is supported by the flexible lighting technology which allows the measurement of steep flanks and materials with varying surface characteristics. The large vertical travel range with a long working distance makes it possible to measure varied component forms and types. Using standards of the PTB (Physikalisch Technische Bundesanstalt, Braunschweig, the national metrology institute providing scientific and technical services) and the DKD (Deutscher Kalibrierdienst) for calibration and adjustment guarantee traceable results.
The high vertical and lateral resolution of InfiniteFocus is based on: » a robust measurement sensor with integrated granite
» a glass scale with a 2nm resolution » specially developed lens
» a high quality and high resolution CCD sensor
» an optical vibration isolation
Area based surface parameters conforming to ISO 25178 » Height parameter (Sa, Sq, ..)

How Focus-Variation works
The specimen is placed onto the stage and is illuminated with modulated light. This light is transmitted through the optic and focused through a beam splitter onto the specimen. Coaxial illumination is created.
The light is reflected by the specimen and projected on to a digital sensor in the precision optic. Depending on the objective selected various lateral and vertical resolutions can be achieved.
As the distance between specimen and objective is varied the change of sharpness is measured. Depending on the 3-dimensional structure of the specimen some areas are depicted sharp or not, the sharp data is used to construct the 3D dataset.
Essential to the measurement result is the correct interaction of modulated illumination with continuous vertical movement and the quality of the sensor measurement. This process is achieved with the SmartFlash technology developed by Alicona.
For every position on the object the sharp regions are measured. The variation of the sharpness values is used for the measurement of the 3D-postion. This is how dense 3D-datasets are created. Technology I alicona

TECHNOLOGY: FOCUS-VARIATION InfiniteFocus is based on the principle of Focus-Variation. It is a robust technology with a high measurement point density including information about measurement uncertainty. Focus-Variation is applied in both research and production.
MEASUREMENT POINT DENSITY AND REPEATABILITY A large number of dense measurement points, also on larger areas, provides highly repeatable measurements. Alicona also automatically provides an estimation of the repeatability of every single measurement value analyzing the variance of each measurement point in the Z-direction. This repeatability measure helps to evaluate the quality of individual measurement points. This again allows measurement results that are easy to interpret. In addition it shows if and to which extend vibrations occurred during the measurement.
InfiniteFocus provides high resolution and reproducible measurement results in both the lab and in rougher manufacturing environments. » The technology works reliably and is not affected by environmental influences such as temperature or ambient light. This is due to the large amount of data that is used for measuring every single z-value. » InfiniteFocus is a high quality measurement device and generally insensitive to external influences. The system includes a vibration absorption construction and is therefore vibration resistant. » Various light sources minimize the impact of light. » InfiniteFocus delivers an estimation of the measurement uncertainty for every 3D-point. 60

FOCUS-VARIATION FROM THE PERSPECTIVE OF A TOOL RESEARCH ASSOCIATION A GUEST EDITORIAL BY HEINZ-WOLFGANG LAHMANN
Heinz-Wolfgang Lahmann from the Society for Production Engineering and Development (GFE e.V.) Schmalkalden/Germany is an expert in the application of optical measurement procedures for the evaluation of precision tools. Among other subjects, he specializes in the metrological characterization of a tool's micro geometry and is familiar with the developments in measurement and test engineering. For basic research on cutting edge characterization he also uses Focus-Variation. From the traceable edge measurement with InfiniteFocus he expects significant progress, which he describes as follows. There is still a huge need in the research on the problem, what impact typical parameters of a cutting edge produce on the processing result. During industry for quality assurance is mainly focused on the measurement of a radius, chipping, wear and micro cracks, research however is dealing with a problem, which additional surface parameters can be used for a functional description of a cutting edge. Recent developments in metrology help us to move forward with relevant activities. This is why, among other factors, the impact of a form of the cutting edge and its roughness is examined as to their influence on the results of processing. Here the Focus-Variation turns to be increasingly establishing itself as an appropriate technology. The area based, high resolution measurements that can be achieved by FocusVariation open new possibilities for research, and, consequently, new insights into cutting edge characterization which was not possible in such a form until now. One of the most significant benefits for us is the fact that we are now able to perform traceable measurements of both geometry and roughness of various edge types.
"One of the greatest advantages, besides the high vertical resolution, is the fact that with FocusVariation we are able to perform traceable measurements of geometry and roughness of different edge forms." The main subject of our current studies is dealing with possible effects that the cutting edge form might produce on the processing result in addition to the edge radius. Therefore every common edge form, ranging from simple edge roundness to a more complex, elliptic form has to be completely measured. At GFE we perform these measurements pri-
Another subject of research is the correlation between a tool and a workpiece. The study examines effects of the material, a tool has been made of, on the machined workpiece or vice versa, how the material of a workpiece affects the tools as for its wear and the like. Here, we benefit from the flexibility of InfiniteFocus as we use the system for the measurement of a tool and a workpiece. For a research association, visualization plays an important role as well. It delivers an additional evaluation possibility for a better analysis of a tool. The visualization in true color information with InfiniteFocus also allows us to detect coated areas quickly and without much effort.
marily by means of InfiniteFocus optical measuring system. Due to a lateral resolution in the submicrometer range and a vertical resolution in nanometer range, the device is ideal for defining necessary roughness parameters. With the 3D measurement device by Alicona we also measure additional parameters such as the roughness on the clearance and chip surface. These parameters analyze the impact of roughness on the machining process, workpiece quality, durability and chip flow.
