Custom optical Cylindrical lens rod lens

optical rod lens

Rod Lenses are a special variant of cylindrical lenses in that they are complete rods where the light passes through the sides of the rod. Rod lenses have an outside face that is polished and the ends ground. Typical uses for rod lenses would be to generate a line image from a circular laser beam.

Rod lenses are polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be focused into a line. These components are used in a variety of laser and imaging applications.
