N-BK7 22mm Diameter Uncoated Littrow Dispersion Prism

Littrow prisms feature 30°, 60°, and 90° angles, can be used for a variety of applications. Uncoated littrow dipersion prisms are used to disperse light into its component spectrum. Coated littrow dipersion prism is used to deviate the line of sight by 60°.

We offer a wide range of different materials and different degrees of precision optical glass prism,including wedge prism,right angle prism,roof prism,rhombohedral prism,Dove prism,Penta prism,pyramid prism,dispersion prism,corner cube prism etc.each having a particular geometry to achieve the reflections necessary to perform a specific imaging task.Rectangular prisms(right angle prism) are used to deflect a beam of light through 90 or 180 degrees. This can be used as component to create various optical devices.Rectangular prism/right angle prism is often used in telescope,periscope and other optical system.BK-7 can be used for a range between the visible and infrared light.Fused-silica can be used for a range between ultraviolet and infrared light.
