Mirrors » Metal Mirrors

Mirrors are used in a wide range of beam steering, focusing, and collimating applications. Metal Mirrors are intended for applications involving lower power lasers or broadband sources. They are less sensitive to wavelength, polarization and angle of incidence than dielectric mirrors.

Solid Metal Mirrors are well suited for use in high power infrared laser applications. Copper must be coated with protected fold or silver because it oxidizes very rapidly. Molybdenum is generally used uncoated. It is a very hard material that does not oxidize and it has high reflectance above 3µm.

Subsrates are available with plano/plano, plano/concave and plano/convex surfaces.
