25mm UV-AR Coated and Aluminized, Fused Silica Penta Prism

Product Details Ray Deviation of 90° Right Handed Image Optical Tool for Defining a Right Angle Additional Penta Prism Options Available Penta prisms are five-sided prisms featuring a ray deviation of 90° and a right handed image. The UV-AR coated options also have aluminized reflecting surfaces for increased efficiency. Slight movement of the prism does not affect the true right angle at which light rays are reflected, making a penta prism the ideal optical tool for defining a right angle in an optical system. TECHSPEC UV Fused Silica Penta Prisms are made from UV fused silica which features low thermal expansion and excellent transmission throughout the UV, VIS, and NIR spectral ranges. Specifications General Type: Penta Prism Physical & Mechanical Properties Dimensional Tolerance (mm): ±0.10 Bevel: Protective as needed Optical Properties Coating: UV-AR & Aluminized Substrate: Many glass manufacturers offer the same material characteristics under different trade names.
