Center Thickness and Surface Spacing Measuring Device OptiSurf Series
This is a device to measure the center thickness of each lenses and the air spacing between lenses in a single lens or a assembly lens. When OptiSurf is installed in OptiCentric, it is possible to measure interplane eccentricity, center thickness, and surface spacing with one unit as OptiCentric3D. There is also OptiSurf UP, which enables more accurate measurement.
Features
- Measure the optical axis eccentricity (approx.10 planes) within 1 minute, and the lens center thickness and spacing within 15 seconds.
- Non-contact measurement using the low-coherence interferometric measurement principle.
