A Penta prisms is a five-side prisms, featuring two important properties. Firstly, the images is neither inverted nor reversed while it is deviated by 90 degree. Secondly, it is a constant deflection device, i.e., all the transmitted rays are exactly deflected by 90 degree. Slight movement of the prisms does not affect the right deflected angle. This feature makes the prisms useful in ra...

Similar to a Plano-Convex lens in profile, but only as a cylinder instead of a sphere, this cylindrical lens focuses light only in one dimension. It can also transform a point image into a line image or charging the height of an image without affecting its width. There are two circumference shapes, rectangular and circular.

Right angle prisms are ideal for beam bending and retro reflection applications. They are often used, instead of mirrors, in applications where deformation of the reflective surface may cause a problem. The fine balance between performance and cost has been optimized making these prisms ideal for OEM applications in the visible and near infrared wavelength range.
