CaF2 Right-Angle Prisms RAP725

CaF2 Right-Angle Prisms — Model RAP725

Operating wavelength 200 nm-8 µm, substrate CaF2.

Product Description

• Optical Material: CaF2
• Working Wavelength: 200 nm-8.0 μm
• Application: Optical Path Deflection

LBTEK offers high-precision right-angle prisms, where selecting different incident surfaces can deflect the light path by 90° or 180°. LBTEK right-angle prisms are available in various materials including N-BK7, UVFS, and CaF2. Based on the principle of total internal reflection, right-angle prisms can function as 90° or 180° reflectors, as illustrated in the diagram above. When light enters through one of the prism's right-angle faces, it undergoes total internal reflection on the hypotenuse face and exits through the other right-angle face, achieving a 90° reflection. When light enters through the hypotenuse face, it undergoes two total internal reflections on the right-angle faces and exits parallel to the incident beam, resulting in a 180° reflection. Additionally, this 180° deflection is independent of the incident angle. Besides the standard version without anti-reflection coatings, LBTEK also provides three broadband anti-reflection coating options: 400 nm-700 nm, 700 nm-1100 nm, and 1100 nm-1700 nm. For anti-reflection coated prisms or other customization needs, please contact LBTEK technical support.

CaF2 Right-Angle Prisms

• Substrate Material: CaF2
• Working Wavelength: 200 nm-8.0 μm
• Application: Beam Deflection

LBTEK offers high-precision CaF2 right-angle prisms, which can deflect the optical path by 90° or 180° by using different incident surfaces. If you are applying them in infrared applications, you can choose LBTEK's CaF2 right-angle prism mirrors.
