Edmund Optics Inc. 25mm Fused Silica Penta Prism UV-AR Coated and Aluminized NT49-023

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 reflecting surfaces are aluminized 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, visible, and NIR spectral ranges.
