HR Coating Optical Glass Prisms 600 Nm ZnSe Right Angle Prisms

Optical glass 600 nm - 16 µm ZnSe High-Precision Right Angle Prisms

high-precision Right-Angle Prisms can be used to deviate a light path by 90° or 180°, depending on which surface is used as the input for the light source. These prisms are fabricated from N-BK7, UV fused silica, CaF2, or ZnSe, and they are offered in sizes ranging from 3 mm to 60 mm. Our N-BK7 right-angle prisms are available uncoated or with one of our three standard broadband antireflection coatings (-A: 350 - 700 nm, -B: 650 - 1050 nm, -C: 1050 - 1700 nm) on either the hypotenuse or both legs, thereby reducing surface losses.

Zinc Selenide is ideal for use in the 600 nm - 16 µm range. It features low absorption (including in the red visible wavelength range) and high resistance to thermal shock. ZnSe is ideal for use in CO2 laser systems operating at 10.6 µm, including those with HeNe alignment lasers. Please see the Graphs tab for a graph of index of refraction vs wavelength for ZnSe.

When handling optics, one should always wear gloves. This is especially true when working with zinc selenide, as it is a hazardous material. For your safety, please follow all proper precautions, including wearing gloves when handling these prisms and thoroughly washing your hands afterward. Due to the low hardness of ZnSe, additional care should be taken to not damage these prisms. Click here to download a pdf of the MSDS for ZnSe.

Map Optics provides OEM of rectangular prism in various sizes, coating options include aluminum film and anti-reflection film, etc.
Right-angle prisms are generally used to bend the image path or turn the light path 90°.
Two rectangular prisms can also be combined together to synthesize images and offset beams of light.
Inclined aluminum prism is recommended for applications with large incidence angles.
