What it is
General reference — not yet source-verifiedAn inspection microscope in semiconductor and microfabrication work is a bench optical instrument for direct visual examination of samples. Inspection microscopes are used to review surface features, check pattern quality, and support manual observation during metrology and troubleshooting.
How it works
General reference — not yet source-verifiedOptical inspection microscopes form a magnified image by directing illumination onto a sample and collecting the reflected or transmitted light through objective optics for viewing or imaging. The operator typically selects objectives, adjusts focus, and changes illumination conditions to emphasize contrast mechanisms relevant to the feature under examination.

Frequently asked questions
What illumination source does the Nikon Optiphot 150 use?
The Nikon Optiphot 150 originally uses an incandescent lamp, which can be replaced with a Cree XML2 LED for improved performance.[3]
What objectives are commonly used on the Nikon Optiphot?
The Nikon Optiphot is commonly used with 10x and 40x objectives; a 100x objective may be present but can be damaged.[2]
What imaging modes does the Nikon Optiphot support?
The Nikon Optiphot supports brightfield, darkfield, and differential interference contrast imaging modes.[4]
