Metallic mirror coating

Metalllic mirror coating is appied to the situation where a consistent high reflection on a wide spectral range is needed. Their reflecatance is lower than dielectric high reflection coating. But their spectrum can cover near-UV, visible and near-IR. Dielectric coating is typically applied on the layer of metallic coating to prevent metallic coating from oxidization. …

How laser beam expander work?

Laser beam expander is a lens assembly which can change the diameter and divergence angle of laser beam. The laser beam emitted from the laser has a certain divergence angle. For laser processing, only by adjusting the beam expander to make the laser beam become collimated (parallel) beam, can the focus lens be used to …
