PS610

• 10 mm leg length for compact optical system integration.
• Manufactured from UV Fused Silica for excellent transmission from the UV through near-IR spectral regions.
• Uncoated optical surfaces provide broadband wavelength capability without coating-related spectral limitations.
• Right-angle prism geometry provides a convenient method for changing the direction of an optical beam by 90°.
• Can utilize Total Internal Reflection (TIR) at the glass-air interface for efficient beam redirection.
• High angular accuracy: ±3 arcmin.
• Suitable for UV, visible, and near-IR optical systems.
• UV Fused Silica offers a lower coefficient of thermal expansion than N-BK7, making it advantageous for applications requiring improved thermal stability.
• Compact 10 mm × 10 mm × 14.1 mm geometry for laboratory and precision optical setups.

The Thorlabs PS610 is a compact 10 mm UV fused silica right-angle prism with uncoated optical surfaces. Its right-angle geometry allows the prism to redirect an incident optical beam by 90° through Total Internal Reflection (TIR) when the appropriate incidence conditions are met.

The prism is manufactured from UV-fused silica, making it well suited for applications spanning the ultraviolet, visible, and near-infrared regions. Compared with N-BK7, UV-fused silica provides higher transmission in the deep UV and a lower coefficient of thermal expansion, making it a suitable choice for demanding optical and photonics applications.

Because the PS610 is uncoated, it can be used across a broad wavelength range without being limited to a specific antireflection coating band. When used as a TIR reflector, the prism can provide efficient beam redirection without requiring a reflective coating on the hypotenuse.

The compact size and precise angular tolerance make the PS610 suitable for integration into optical assemblies, laser systems, imaging setups, and research instrumentation.
