NanoFab Tool: Nikon L200 Compound Optical Microscope

Photograph of the Nikon L200 compound optical microscope.

The Nikon L200 is a compound optical microscope that supports both reflected light and transmitted light modes for inspecting substrates and samples. The microscope provides a wide range of imaging and inspection techniques utilizing brightfield, darkfield, and Nomarski differential interference contrast (DIC) methods at magnifications ranging from 100 times to 1000 times. An integrated five megapixel camera can capture high magnification, high resolution digital images of substrates ranging from 150 mm diameter wafers down to small pieces.
