Interferometers are used for a wide variety of applications. Examples are testing of flatness and sphericity of optical surfaces, radius measurement and the testing of the wavefront of optical systems. Möller-Wedel interferometers are available in many sizes and setup combinations. View the interferometer catalog for information on possible setup combinations and other technical specifications.
Interferometers are an indispensable measurement tool in optical production and quality control.
SIAM – Secondary Image Angle Measuring InstrumentRead more

Hilger-Chance Refractometer w/ Software, Multiple WavelengthsRead more
The Vermont Photonics HCDR is a refractometer that uses the Hilger-Chance method to measure the refractive index of glass slugs cut at 90º.
SurfaceView Flatness Measurement SoftwareRead more
Flatness measurements are made as a series of single angle measurements at specified locations. Electronic autocollimators are some of the most accurate instruments for the small angle measurements required for a flatness measurement.
