Product Family Description

  • 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 – 7µm, making them ideal for applications requiring high transmission from the UV through the IR. Ge equilateral prisms are transmissive from 2 – 14µm with a high index of 4.002 at 11µm and are used in applications where the optical path length needs to be maximized. ZnSe equilateral prisms have high, even transmission from 0.6 - 18µm and are typically integrated with CO2 laser systems that feature a 632.8nm HeNe alignment laser and 10.6µm output beam.
