MEASUREMENT DESCRIPTION Zygo NewView 200 Laser Interferometers Laser interferometers use a frequency shift of a primary laser to set up a vertical “fringe pattern” on a part and then identify “focus” by sweeping the lens through a typical Z range of 40µm [1500µin] using piezo-electric motors and looking for the sharpest contrast. This Z focus is recorded for each of 240 x 320 pixels in the adjustable field of view. Z resolution of 5 nanometers [.02µin]. Zygo Mesa Laser Interferometer Same technology as NewView 200 above but with larger field of view and Z resolution of XXX Nikon NEXIV VMR-3020 CNC Video Measurement System Premium non-contact coordinate measurement system. Automatically compares data to complex tolerance zones for GD&T compliance. X&Y resolution of 0.1µm [4µin]. RAM OMIS III CNC Video Measurement System Glass stage encoder XY coordinate measurement system. X&Y resolution of 0.5µm [20µin]. Nikon V12 Optical Comparator Large screen comparator with QC 2000 digital processor and 1.2µm [50µin] resolution X&Y stages. Wilson-Tukon 2000 Micro-hardness Tester Diamond indentation hardness tester with adjustable brale and dwell time and 100X-500X filar measurement.
