1. Aspherical and spherical mirror are used for focus adjustment, convergence, project image with low color aberration. Reflection mirror applications are from laser beam confinement to instrument sub-assembly and high performance image. Especially, long focal length reflection mirror conveniently applied to laser beam alignment.
2. Plane mirrors are massively used on camera, CD player, and VCD/DVD player. The requirements of size, roughness, and cleanness are very high. COT provides them into industry for many years.
