Features
Total Internal Reflection
By means of total internal reflection (TIR), a right-angle prism may be used as a 90° reflector or as a 180° retroreflector. Except for reflection losses from the entry and exit faces, TIR exhibits 100% reflectivity over a very broad wavelength range. The reflecting surface should be coated with protected aluminum if the incidence angle exceeds that acceptable for TIR or if the environment does not allow the reflecting surface to be kept clean, as TIR requires.
N-BK7 for VIS and NIR Applications
High Quality Precision Prism Surfaces
Broadband Visible Antireflection Coating
1064 nm Laser Line Antireflection V-Coating
Our AR.33 laser line V-coating offers the lowest reflectance (maximum reflectivity per surface <0.25%, 0º-15º AOI) at 1064 nm for maximum transmission while maintaining high durability and high damage resistance. Valuable laser energy is efficiently transmitted rather than lost to surface reflection and scattering. The trade off to its superior performance is the minimal laser line wavelength range.
