Equipment
- White light and 3-wavelength interferometers for the testing of discontinuous surface profiles in the micro region
- Fizeau interferometer for the testing of plane and spherical surfaces
- Twyman-Green interferometer for the testing of micro and macro lenses in reflected light (sphericity, radius)
- Mach-Zehnder interferometer for the testing of micro lenses in transmitted light (wave aberrations, PSF, MTF, focal length, NA)
- Grazing incidence interferometer for the testing of acylindrical lenses for the beam shaping of semiconductor laser bars
- Shack-Hartmann sensor for wavefront testing
