Mirror

・Laser Mirror: Laser mirror is characterized by a dielectric coating optimized to have a high reflectance at a specific laser wavelength. These mirrors typically receive a damage threshold test and are used in the most popular laser wavelength.

・Metal Mirror: As a metal coating mirror including Al, Au, Ag, Cu, Cr, etc., reflectivity and uniformity of the broad wavelength are excellent.
