Penta prism is a five-sided glass block, it can deviate the angle of incident beam or image to exact 90° without any inverting and reversing, whatever the angle of incoming beam is. This kind of prisms is widely used in optical observation system and measuring applications.

Hangzhou Shalom EO offers penta prisms with a wide wavelength range from UV, Visible to IR spectrum.
