• High Laser Damage Threshold
• <0,25% Reflection for Nd:YAG Applications
• A Wide Variety of Nd:YAG Laser Line V-Coats
TECHSPEC® Laser Line Right Angle Prisms provide high damage thresholds ranging from 2 - 5 J/cm2 allowing
for easy integration into most Nd:YAG laser systems. Our TECHSPEC® Precision λ/10 Laser Line Right Angle
Prisms feature a 40 arcsec angle tolerance, making them ideal for laser-based applications requiring precision
alignment. Our TECHSPEC® High Precision λ/20 Laser Line Right Angle Prisms have a 15 arcsec angle tolerance,
making them ideal for beam steering with minimal wavefront distortion and consistent alignment. All
prisms feature < 0,25% reflection of common Nd:YAG laser lines.

Laser Line Right Angle Prisms
• CaF2, Ge, and ZnSe Substrates
• Ideal for Wavelength Separation
• Designed for Use with Collimated Sources
Infrared (IR) Equilateral Prisms, also referred to as dispersion prisms, feature three equal 60° angles and are used
in wavelength separating applications. These prisms are available with calcium fluoride (CaF2), germanium (Ge),
or zinc selenide (ZnSe) substrates. CaF2 equilateral prisms offer a low refractive index and broad transmission
range from 0,2 – 7 μm, making them ideal for applications requiring high transmission from the UV through
the IR. Ge equilateral prisms are transmissive from 2 – 14 μm with a high index of 4,002 at 11 μm and are used
in applications where the optical path length needs to be maximized. ZnSe equilateral prisms have high, even
transmission from 0,6 - 18 μm and are typically integrated with CO2 laser systems that feature a 632,8 nm HeNe
alignment laser and 10,6 μm output beam.
