Metal-Coated Plano Optical Mirrors

High-quality, metal-coated optical mirrors are available for use with light throughout the UV, VIS, and IR spectral regions. Their relatively wide bandwidth and high reflectivity makes mirrors with metallic coatings ideal for applications like spectroscopy.

Paralight Optics offers custom metallic mirrors available in Custom optic sizes, geometries, substrate materials, and coatings.

Paralight Opitcs offers mirrors with protected aluminum, silver, and gold coatings which exhibit exceptional broadband reflectance and are practical for many applications that are insensitive to the wavefront of a beam. Other typical uses for these mirrors include single-use applications where the experiment itself damages the mirror.
