Measurement of optical and glass thicknesses

OptiSurf® is a range of instruments ideal for non-contact measurement of optical thicknesses of plates, lenses, objectives, waveguides, or complex optical sub-assemblies. These instruments are based on the principle of Low Coherence Interferometry, and can measure any distance between surfaces in an optical system with micrometric precision. The OptiSurf® LTM version is designed to measure the thickness of single, doublet or triplet lenses. The Optisurf® PRO version is designed to measure waveguide thicknesses.
