How to use a Compound Microscope
What is a compound microscope A compound microscope has two lenses. The objective lens is used to collect light from the object The eyepiece is the lens which is used to magnify the light from the objective lens The compound microscope gives an enlarged inverted virtual image of the object in focus
Controversies regarding who invented Compound Microscope The Dutch spectacle-maker Zacharias Janssen is sometimes claimed to have invented it in 1590 (a claim made by his son and fellow countrymen, in different testimony in 1634 and 1655) Another claim is that Janssen's competitor, Hans Lippershey, invented the compound microscope Another favorite for the title of 'inventor of the microscope' was Galileo Galilei. He developed an occhiolino or compound microscope with a convex and a concave lens in 1609.
Components Eyepiece is the ocular lens to view the object Objective turret, revolver, or revolving nose piece to hold multiple objective lenses Focus knobs to manipulate and adjust the focus Light source to illuminate the object.
Enhancement techniques used For higher resolution oil immersion or water immersion is used to obtain greater resolution Powerful light source is used to illuminate the object so that the object to be seen has more visibility Condenser is used to converge light source to the object to illuminate the object Fine adjustment of the stage or the platform to enable the viewer to get the image of the object
Advanced techniques Several advanced techniques are now employed enhancing the image obtained such as Fluorescence microscopy, both:Microspectroscopy where a UV-visible spectrophotometer is integrated with microscope Ultraviolet microscopy Near-Infrared microscopy
