Scanning Mirror

Scanning Mirror

The scanning mirror applications include ultra-high dynamic, low inertia scanning mirrors for laser processing, streak cameras, LIDAR, security, sensing and targeting applications, where the enhanced flexural strength, homogeneity, high resonant frequencies, ultra-low inertia, and optical surface quality are key.

Description Of Scanning Mirror

The scanning mirror of BRD Optical is light weight rectangular mirrors that used for high speed two-axis laser scanning system. The dimensions for each mirror have been calculated accordingly with the laser beam size. The optical mirror has high reflectivity of 99.5% or above. The scanning mirror usually mounted on to a galvanometer for scanning purposes. For two axis scan mirror, commonly the Y mirror has a bigger size compared with 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.
