The Nikon MM 400 is a measuring microscope.[1]
What it is
Nikon MM 400 is a measuring microscope.[1]
How it works
General reference — not yet source-verifiedMeasuring microscopes utilize a compound optical system with an objective lens and eyepiece to produce a magnified image of the workpiece. A precision stage moves the sample in two axes, and an integrated measurement scale or digital encoder records position coordinates for distance, angle, or radius measurements.
Applications
General reference — not yet source-verifiedPrimary applications include measurement of line widths, overlay registration, feature placements, and defect review on semiconductor wafers and photomasks. The instrument is also used in metrology of MEMS devices, micro-optics, precision mechanical parts, and other microfabricated structures.
