Trapezoidal Prisms – Precise Beam Displacement & Image Rotation
Specifications:
-
Material: Optical Glass (N-BK7, H-K9L), Fused Silica
-
Dimensions: Custom sizes; typical base lengths 10–100 mm
-
Angles: Standard trapezoid angles (e.g., 45°-90°-45°) or custom geometry
-
Surface Accuracy: λ/2 – λ/8 (@ 632.8 nm)
-
Surface Quality: 40-20 or 20-10 Scratch/Dig standard
-
Coating: Uncoated, or with broadband AR/V-coat on request
Primary Applications:
-
Beam Steering & Displacement: Shift optical path without changing direction
-
Interferometry & Metrology: Create reference or probe beam offsets
-
Imaging Systems: Compact periscopes and image rotators
-
Laser Systems: Assembly of ring lasers or folded cavities
-
R&D & Prototyping: Versatile component for custom optical layouts
