Interferometric Profiling Instruments

XPER IP Mini_logo_standard.png

Thickness is a typical parameter related to length, measurements of which are conducted in various industrial fields, such as the automotive, aviation, ship-building, semiconductor, and display industries. 

Among various measurement techniques, optical interferometry is by far one of the most attractive ones for its reliability owing to the direct realization of the meter. Moreover, the nature of this non-contact method of optical interferometry does not damage samples. Xper-IP Mini is the outcome of
 such interferometric methods realized for measuring thicknesses of thick transparent layers.
