Glass High Precision Prism 180 Nm CaF2 Right Angle Prism

Optical glass 180 nm - 8 µm CaF2 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.

Choose a CaF2 Right-Angle Prism for applications requiring high transmission in the 180 nm - 8 µm range. The material exhibits a low refractive index, varying from 1.35 to 1.51 within its usage range of 180 nm to 8.0 µm, as well as an extremely high laser damage threshold.  Calcium fluoride is also fairly chemically inert and offers superior hardness compared to its barium fluoride, magnesium fluoride, and lithium fluoride cousins.

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.
