High-Speed Two-Axis Galvo Scanning Mirrors – Lightweight Rectangular Design with >99.5% Reflectivity for UV to IR Lasers

Scanning mirrors are light weight rectangular mirrors used for high speed two-axis laser scanning systems. The dimensions for each mirror are calculated accordingly with the laser beam size. The mirror is designed with high reflectivity of 99.5% or above. The scanning mirror is generally mounted onto a galvanometer for scanning purposes. For two axis scan mirrors, commonly the Y mirror has a bigger size compared to the X mirror. This is due to the fact that the X mirror is used to scan the Y mirror rather than the object directly.
