Question

To determine the radius of Carvature of
oncave mirror using a spherometer.

Answer 1

Radius of Curvature is a critical design parameter in optical manufacturing. Many of ZYGO's optical interferometer products can be used to make high-accuracy radius of curvature measurements by measuring the distance between "cats eye" and confocal positions. This requires the purchase of a position measurement system consisting of either a linear encoder scale or, for extremely high accuracy measurements, ZYGO's distance measuring interferometer system. ZYGO's proprietary Radius of Curvature application for the MetroPro® analysis software is also required.
