utting, welding, marking, processing surfaces – more and more manufacturing technology experts are valuing the flexibility, versatility, and cost efficiency of the laser tool. At TRUMPF, you will find the right laser for any task. We offer you advice and support on how you can build your Smart Factory step by step by networking your lasers with software, machines, and services, and therefore how to equip yourself for the digital future of your production facility. Types of laser products available with TRUMPF - Disk laser, Diode laser, Ultra-shot pulse laser, Fiber laser, Marking laser, Pulsed laser, CO2 laser, Scientific laser, Sensor system and Processing optics. Laser material processing has digital bits encoded in its DNA. From day one, numerical control was the only option for engineers wishing to gain mastery over light, and they have since gathered 50 years of experience with this incorporeal phenomenon. This is a huge advantage for those tackling the challenges of the modern world in general and data-driven manufacturing in particular. The laser is a fully mature industrial tool that meets all requirements and can be immediately put to work. It is swift, flexible and direct. Ablation, coating, drilling, cutting, joining, metallurgical transformation, tempering glass, and roughening, smoothing or cleaning surfaces: laser light can do it all. There’s no material in the world that laser beams can’t process: glass, plastics, organic compounds, and every type of metal. If smart factories are in their infancy, lasers are already “grown-up.”
• 100% consistent power output Stable processes through integrated, active laser power control ensure reproducible results. • Robust against reflection The patented resonator design means that your TruDisk can also process highly reflective materials. • Low-spatter welding With BrightLine Weld you can achieve high-quality welding seams with minimal spatter formation. • Maximum beam quality As a laser medium, the disk in the TruDisk ensures brilliant beam quality up to 2 mm·mrad. • Intelligent energy management Multiple energy-saving modes and the power factor correction reduce the power requirement. • Flexible cooling concept Choose between an integrated heat exchanger (standard) and compressor cooler (optional).
Lasers Don’t Care What You Ask Of Them The trend toward ever more product variants, special editions, personalization and Flexible batch sizes has spread to almost every sector of industry. This has driven up the cost of mechanical tools and led to absurdly long retooling times – sometimes longer
than the actual production process. Lasers, by contrast, require neither special tools nor retooling. The major automotive companies have long since eliminated all mechanical machining steps downstream from the forming press, such as milling or drilling, and have set up laser stations instead. When designing car doors, for example, the raw body part is cut in such a way that it can be used in the maximum number of different models. In the subsequent processing stages, it makes no difference to the laser whether

the angles have to be flatter for the soft-top version or wider holes have to be drilled for the station wagon version. The data package gives the instructions, and the laser executes them immediately. Intelligent scanner optics require nothing more than the data from the 3D simulation software to direct the laser to the right weld spots – without having to be taught. The tool adapts automatically to the workpiece. From drilling the finest holes no wider than a hair, to welding panels in ship building, the disk lasers from market leader TRUMPF have been used in tens of thousands of installations around the world, impressing customers through maximum component quality and laser reliability. Whether it be a continuous wave or ultra-short pulse laser, disk laser technology demonstrates its advantages in the respective sector with both high pulse energies and high average powers. The lasers are particularly easy and flexible to integrate due to intelligent activation concepts with high functionality. The TruDisk is a high-power solid-state laser for the welding, cutting, and surface processing of metals. It impresses above all in situations which require the combination of high power and maximum beam quality. The new generation of TruDisk lasers provides you with great advantages, above all due to its much more compact footprint and increased robustness. It also has intelligent inner parts. The data quality of the sensor systems which monitor all the important parameters in the laser has been improved significantly so that the new TruDisk lasers are perfectly prepared for future Industry 4.0 services such as condition monitoring. The TruDisk operates economically in all laser states due to increased efficiency, a new pulse function with increased energy efficiency, and intelligent energy management.

TOS is showcasing scientific imaging, spectroscopy products and x-ray high energy imaging (10eV to 100 KeV & beyond) products at LWOP India 2019, at Hall 4, Booth number 4025. Balor is Andor’s game-changing, very large area sCMOS camera platform for Astronomy. It launches with the Balor 17-12 model, featuring an enhanced FoV 16.9 Megapixel, 70mm diagonal sensor, coupled with fast, low noise readout capability. Balor is ideal for measuring photometric and astrometric variability from milliseconds to tens of seconds timescales. Balor is the largest commercially available sCMOS camera, designed for ‘dynamic astronomy’ applications such as Orbital Debris tracking, Solar Astronomy, Solar System Object detection, Exoplanet Discovery, Atmospheric Studies and Fast Time Resolution Astrophysics. Balor lends itself particularly well to the ‘atmospheric freezing’ techniques of Speckle/Lucky Imaging, enabling resolution enhancement of ground-based astronomy over a much larger field of view than is readily achievable through use of adaptive optics. Balor combines 2.9 e- read noise with an exceptionally fast 18.5 millisecond readout, allowing up to 54fps full frame readout, perfect for studying solar or atmospheric dynamics. The faster readout capability, 2500x faster than CCDs, also renders Balor superb for exoplanet discovery, radically compressing measurement cycle times and allowing more time to instead be spent capturing scarce photons. Balor outperforms in the area of quantitative photometric measurement. Complimented by a marketleading linearity of > 99.7%, the large 12 µm pixels offer

an 80,000 electron well depth and an on-chip multiamplifier design means the whole photometric range, from the noise floor up to the saturation limit, can be captured with one image. Such capability is ideal for photometric accuracy of light curve measurement across high dynamic range object fields. Balor delivers both Rolling Shutter and Global (Snapshot) Shutter exposure modes. The latter can be useful for applications where every pixel across the array must carry the same relative exposure timing correlation, relative to an external timestamp. Balor is Perfect Detector Solution for Astronomy The launch of Balor was announced on September 3, 2019. Balor is the perfect detector solution for large sky surveys that measure photometric and astrometric variability across timescales ranging from milliseconds to tens of seconds. Minimizing down-time in astronomy is paramount; not only does Balor avoid the need for a mechanical shutter, Andor is the only camera manufacturer with capability to apply an innovative hermetically sealed, permanent vacuum enclosure design to the sCMOS sensor technology. This uniquely protects the delicate sensor from attack by moisture and other gas contaminants, thus preserving both QE and stable cooling performance year after year, removing the need to have the camera re-pumped. Dr Colin Coates, Product Manager, said; “Many challenges in modern astronomy require not only high resolution, large field of view and superb sensitivity - they also require faster measurement
rates. However, large area CCD technology is very much performance-limited in this regard, typically requiring more than 40 seconds to read out a single frame. The new Balor sCMOS platform addresses this fundamental application shortfall, reading out 2,500 times faster than CCDs. Balor’s frame rate is ideal for solar astronomy, capable of imaging entire sunspots with high spatial resolution while measuring fast solar dynamics. The faster readout capability also renders Balor superb for exoplanet discovery, radically compressing measurement cycle times and allowing more time to instead be spent capturing scarce photons.” Dr Ines Juvan-Beaulieu, author of the Exploring New Worlds blog, and Andor’s Astronomy Specialist, said; “As well as offering enhanced sensitivity and dynamic range, the large sensor area will help our ground-based astronomy customers to perform photometry and astrometry across larger areas of sky, ideal for improved statistics of detection when tracking solar system objects - imaged directly or via occultations. Balor lends itself particularly well to the technique of Lucky/Speckle Imaging, enabling resolution enhancement of ground-based astronomy over a much larger field of view than is readily achievable through use of adaptive optics.” Fast Sensor Readout The sCMOS sensor in Balor 17F-12 has highly parallel readout architecture, facilitating high data readout rates. Taking only 18.5 milliseconds per full frame readout, Balor 17F-12 can measure variability across a wide range of timescales. It is also possible to maximize SNR by using longer exposures and still achieve frame cycle times much faster than CCDs. Photometric exposure times in the tens of seconds are commonplace for transit or radial velocity measurements. When performed with a 4k x 4k format CCD with 4 output ports, a low noise readout requires an additional 45 seconds on top of the exposure. Balor has an 18.5 ms low noise readout, approximately 2500x faster than a CCD! The exposure scheme below shows how, using a 10 sec exposure time, the measurement cycle time can be significantly shortened with Balor. Even when we lengthen the Balor exposure time to 15 sec to achieve the same SNR as a back-illuminated CCD, the duty cycle remains much shorter. Thus, Balor is an opportunity for enhanced SNR and temporal resolution combined. Balor also avoids the need for routine replacement of mechanical shutters. Extended Dynamic Range and Superb Linearity The innovative Multi-Amplifier architecture of the Balor sCMOS sensors uniquely circumvents the need to choose between high or low gain amplifiers, in that signal can be sampled simultaneously by both high gain (low noise) and low gain (high capacity) amplifiers. As such, the lowest noise of the sensor can be harnessed alongside the maximum well depth, affording a wide dynamic range. Furthermore, on-camera intelligence delivers a significant linearity advantage (> 99.7% linearity), providing unparalleled quantitative measurement accuracy across the full dynamic range.

features dedicatedly engineered for industries, the company makes the machine with inbuilt 3G Marking with OPTI FLY integrated with Poka Yoke Mechanism. With the capability of the in-house R&D team, SLTL Group is equipped to conduct forward and backward integration of automation and machines. OPTI FLY works with intuitive in-house software and hardware neural system integrated with laser machines. It could be integrated with laser systems of your choice. The system follows the following processes without any human interference: Identify: once the objects begin moving on the conveyor. The very initial method that takes place is termed ‘identify’ because it identifies the fundamental form of the article and compares it with knowledge already fetched in the database. Locate: Throughout this method, the package is already ready with parameters and signatures which will facilitate the system to find the realm of operation. ‘Locate’ is one in each of the necessary functions of the system because it can permit right position to induce operated. Orient: As per the known object and set space of marking in the previous method, the system fetches the information and guides any changes. Throughout ‘orient’ method the smart intuitive software makes adjustments to the drawing for the marking process to take place. The direct connection between the laser marker and therefore the vision system enable the practicality for position correction because the
laser marker requests the coordinates from the OPTI FLY system. Mark: Once the article is being known to its form, set the marking space supported parameters and orienting as per the appropriate position; the marking method takes place. The article is operated with optical laser and results area unit obtained. Verify: Verification method is like quality checking method done by the system itself. Throughout this method, the system with pre-compiled knowledge cross-checks with the important pictures of the objects through vision camera and verifies if the system has done the marking operation or not. The verification method is to assure that no object is incomprehensible on the road while not marking operation in alternative cases knowledge and images of what being marked should be saves for traceability functions. Sort: once verification method, there comes a method to assure that marking on the article is in step with pre outlined customary and quality. This is often associate degree assurance method that makes certain the best on the lines gets through whereas eliminating the issues. The system can check the marking surface on the article through advanced vision systems and declares ‘ok’ and ‘not ok’ on the screen. That any ‘not ok’ merchandise area unit is eliminated. SLTL Group has in-house R&D and has delivered many customized automated solutions to numerous industries. The company is celebrating 30 years of operations and promises to empower industries with continuous innovation.
