Right Angle Prisms

• Laser or laboratory quality
• Fused Silica or Glass
• 90 or 180 degree reflection
• Antireflection coatings available

A Right Angle Prism is used to turn or deflect a beam through 90° or 180°. In either case this is achieved by total internal reflection and produces a very efficient broadband reflector. It is important that the incoming beam is collimated and enters the prism at a normal angle of incidence. This is so that total internal reflection can be achieved. A range of both laser and laboratory quality prisms are available. These are available in either fused silica or BK7 glass.

Laser Quality

Ealing offers a range of laser quality right angle prisms. These have been manufactured with high precision and selected for low scatter. Surface finish and angular accuracy are tightly maintained. Fused silica is an ideal material for most laser applications because of its thermal handling capabilities. Glass is recommended for lower power applications.
