Rhombohedral prisms are commonly used to offset laser beams without changing their direction. In imaging applications, a rhombohedral prism will offset the optical axis without inverting the image. The lateral displacement is equal to the length of the prism. 

Our rhombohedral prisms have highly precise angles, ensuring that the parallelism between the output beam and the input beam is within 30 arc - seconds. They are suitable for applications requiring positional offset.
