New Rise Optics 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
