Partial Reflector/Output Coupler(UV, Visible, IR) 

·Controlled reflectance at the wavelength of interest ·High power applications, Low scatter ·Output couplers, Beam dividers Partial reflectors provide a known reflectance at the wavelength of interest. They have an anti-reflection V-coat applied to the rear surface. Reflectance and wavelength may be chosen by the user. The range and tolerace of reflectances offered and the common laser wavelengths are listed in the table. Partial reflectors may be used as laser output couplers. Remenber that the refletivty chosen determines the gain of the laser; high gain requires low reflectivity. An appropriate output coupler should be selected to maximize the output power/energy ratio. Note that Lambda high quality laser cavity coatings are designed for low scattering. Part NO.                              Reflectance(%)                 …
