Low-Coherence Interferometer for Center Thickness and Air Gap Measurement
within UV, VIS and IR Lenses

OptiSurf® is the ideal tool for non-contact center thickness and air gap measurement of single lenses, planar optics and optical systems. The instrument is based on low-coherence interferometry and measures all distances in an optical system with an accuracy of up to 0.15 μm in one scan.

OptiSurf® is outstanding in compactness and ease of use as it incorporates all measurement and alignment components in a single system. It can either be used as a standalone system or in combination with OptiCentric®. Due to the compact footprint of the measurement head, OptiSurf® can also be incorporated into a customized application.
