Optical Mirrors

Optical mirrors are available in two grades (precision and commercial) to meet various specific applications.

Precision Grade Optical Mirrors

  • Catalog optical mirrors made of either low expansion borosilicate glass or fused silica.
  • Various substrates including N-BK7® and ZERODUR® available.
  • Polished up to λ/20 to meet various demanding applications.
  • Custom optical mirror sizes and shapes available upon request.
  • Available either uncoated or with a variety of reflective coatings including: bare Al, protected Al, bare Au, protected Au, enhanced Al (one specifically designed for the visible region of the spectrum and one for the ultraviolet region) Custom optical coatings available upon request.
  • Most of our optical mirrors are available in-stock for immediate shipment.

Need help correctly specifying an optical mirror?

Front surface optical mirrors, also known as first surface mirrors, are precision polished and coated to reflect light of specific wavelength(s). For an optical mirror to perform as expected having a good understanding of your application, as well as specifying the correct optical characteristics, is essential to reducing costs and procuring the perfect mirror.

Careful consideration should be given to the following and provided when requesting a quotation for an optical mirror.
