Opt⚙City ®-Quality Crystal & Optical Components
These dielectric coated HR mirrors are highly efficient over a broad wavelength range. Both bragg mirror, where all optical layer thickness values are just one-quarter of the design wavelength, and more complicated multilayer structure designs are used to obtain desired reflection. Dielectric coated HR mirrors are durable and will withstand repeated cleaning.

Standard sizes: Dia.12.7 x 3, Dia.25.4 x 6, Dia.50.8 x 9.5 mm
Wavelength: 450-700 nm, 700-950 nm, 950-1200 nm, 1064 nm, 532 nm, 267 nm. Other sizes and wavelength HR Mirror including Laser Cavity Mirror, Output Coupler are also available.
Notes: Due to the structure of the multilayer deielectric coating, the spectral range over which the mirror is highly reflective shifts toward longer wavelengths as the angle of incidence decreases to zero.
