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.
UV Fused Silica for UV, Laserline & Broadband Applications
High Quality Precision Prism Surfaces
Our precision prisms are polished to tight tolerances minimizing wavefront distortion. Tight surface quality tolerances minimize scatter and unwanted diffraction effects. These right angle prisms have a 10-5 scratch-dig surface quality (10SR25 is 20-10 scratch-dig), and a λ/10 surface flatness.
Broadband Visible Antireflection Coating
Broadband Multilayer NIR Antireflection Coating
Our AR.16 coating is recommended for NIR applications in the 650-1000 nm range.
Broadband Multilayer IR Antireflection Coating
Our AR.18 coating is for IR applications in the 1000-1550 nm range.
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.
