Right Angle Prisms

Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.

• Material: BK7 glass, UV grade fused silica
• Flatness: <λ/10 @ 633mm
• Surface Quality: 10/5 scratch & dig
• Dimension Tolerance: ±0.051mm
• Angle Tolerance: up to 5"
• Clear Aperture: ≥95%@central area
• Bevel: 0.2mm(typical)x45

Right Angle Prisms,Uncoated

• Total internal reflection prisms
• 90°or 180°beam deflection

Right Angle Bending,Prisms

• 90°reflectors

Right angle bending prisms are anti-reflection coated on the legs. Optionally, the hypotenuse may be coated with second-surface aluminum protected by black paint to ensure grazing incidence reflection. These prisms are suitable for optical delay lines and for high power use

Right Angle Folding Prisms

• 180°reflectors
• Aluminum on legs and AR on hypotenuse

Folding prisms are intended for use as 180°reflectors. An anti-reflection coating is applied to the hypotenuse. Second-surface aluminum protected by black sealing paint is applied to the legs to ensure grazing incidence reflection. These prisms are suitable for optical delay lines and for high power use
