It can also be used for projects such as asphericization of large spherical mirrors!
We offer custom mirrors with high-precision aspheric and freeform surfaces.
By combining our unique technology, the CGH (Computer Generated Hologram) high-precision shape measurement technology with robotic polishing technology, we have made it possible to manufacture high-precision mirrors in various shapes with virtually no shape limitations.
The materials that can be polished include not only common mirror materials such as synthetic quartz and low-expansion glass ceramics (Zero-Dur, ClearCeram) but also various types of optical glass.
