Product description: The OptiCentric® 3D Mirror Spacing and Centre Deviation Gauge can be used to measure the centre deviation of optical systems, as well as the air spacing between lenses and the centre thickness of lens
INQUIRY

OptiCentric® 3D mirror spacing and centre deviation measurement - non-contact measurement of individual centre deviations and air spacing in optical systems, etc.

OptiCentric® 3D was developed by combining the functions of the OptiCentric® centre deviation meter and the OptiSurf® mirror positioner. It measures not only the centre deviation of the optical system, but also the air spacing between lenses and the centre thickness of the lenses. Since both centre deviation and mirror spacing can be measured on the same device, this greatly facilitates the high-precision mounting of optical systems.
