Product Description

Optical Testplate for Testing the Flatness of Spherical and Plano

 
Optical template
Optical templates (prototypes) are divided into several types: optical templates include standard templates, working templates, and flat templates. The prototype is a shape template based on the phenomenon of light wave interference to measure optical surface errors, and has become the most widely used and convenient precision measurement tool in the manufacturing process of optical parts. Therefore, its surface accuracy is higher than that of ordinary optical parts. To ensure quality, the spherical surface is preferably manufactured in pairs of concave and convex surfaces, and repeated instrument measurements are required during the processing to ensure accuracy.
