Optical Prisms
Right Angle · Wedge · UV Fused Silica & H-K9L
Precision prisms for beam deflection, retroreflection, and beam steering. Available in UV fused silica for UV and near-IR laser systems, or H-K9L for visible-wavelength applications. Angle tolerances to < 30 arcseconds.
Right Angle Prisms
UV Fused Silica · H-K9L (N-BK7 equiv.)
Right angle prisms deflect a beam by 90° or retroreflect it 180° via total internal reflection (TIR). In TIR mode, no reflective coating is needed on the hypotenuse, giving very high throughput without metallic coating losses. UV fused silica versions are suitable for UV laser systems.
Wedge Prisms
UV Fused Silica · H-K9L (N-BK7 equiv.)
Wedge prisms introduce a small angular deviation to a transmitted beam. Two identical wedge prisms rotated relative to each other (Risley pair configuration) provide continuously variable beam steering over a circular field. Widely used in laser aiming systems, interferometry, and beam-pointing correction.
