Trapezoid Prisms – Beam Shift & Image Translation
Detailed Description:
Trapezoid Prisms (Rhomboid Prisms) are parallelogram-shaped prisms that laterally shift the optical path without changing the direction of light propagation. They are used to displace a beam or translate an image in interferometers, alignment systems, and optical delay lines.
Key Specifications:
Materials: BK7, Fused Silica
Size: 5mm – 100mm
Shift Distance: Customizable (based on prism dimensions)
Angle Tolerance: ±1′ ~ ±5′
Surface Quality: 40/20, 20/10
Coating: AR coating on input/output faces
Parallelism: High parallelism to maintain beam collimation
Applications:
Interferometers, optical delay lines, beam alignment systems, imaging systems, laser metrology.
