What it is
The Zygo Mark D II is an interferometer. The Zygo Mark D II is categorized under precision optics.[1]
How it works
Where it fits in the process flow
General reference — not yet source-verifiedPrecision optical interferometers are metrology tools rather than production process tools. Precision optical interferometers are typically used around optical fabrication, assembly, qualification, failure analysis, and laboratory inspection steps where surface figure or transmitted wavefront must be checked before or after polishing, coating, bonding, or alignment operations.
Applications
General reference — not yet source-verifiedInterferometers are used to inspect optical components such as flats, lenses, mirrors, windows, prisms, and reference surfaces. Interferometers are also used in precision manufacturing and research settings where noncontact evaluation of surface quality or alignment is required.
