Optics >>> Mirror

Red Optronics offer a variety of Laser quality mirror with dielectric(HR) coatings and metallic coatings that include Aluminum(Al), UV Enhanced Al, Silver(Ag) and Gold(Au). Mirror substrates include BK7, Pyrex, UV Fused Silica and Zerodur.    

In addition, we are capable of offering customized mirrors that can 

  • Simultaneously high reflecting on two wavelengths

  • Second and third harmonic of laser radiation

  • Highly reflecting at one wavelength while transmitting another wavelength

  • Broadband coating mirrors

  • Dielectric coatings that are polarized and depolarized

When ordering customized mirror, please specify the following 

  • Dimension and tolerance

  • Substrate 

  • Coating and wavelength

  • Polarization

  • Flatness
