Penta Prisms

90° Deviation of input beam
Does not invert or reverse the image

Penta Prisms deviate an input beam by precisely 90°.In imaging applications Penta Prism will neither invert nor reverse the image. These prisms deviate a beam through same angle regardless of its orientation to the beam. The reflecting surfaces of our Penta Prisms are coated with protective aluminium. The entrance and exit surfaces are single layer anti-reflection coated in HO-PPC series.
