Product Case Studies

The Dawei prism can be considered as a right angled prism with a cut top, which reduces the weight of the prism and internal reflection of stray light. They introduce astigmatism when used for converging light beams, so we recommend using them for collimated beams. In addition, these prisms can also affect the polarization state of the transmitted light beam.

In a Dorian prism, light usually propagates along the longitudinal axis of the prism. The lower left and middle images show this configuration, where light undergoes one reflection at the bottom and forms an inverted image on the other side of the prism. Rotating the prism along the longitudinal axis will cause the image to rotate at twice the rotational speed of the prism. For example, when the prism rotates 20 degrees, the image will rotate 40 degrees. The Dawei prism coated with anti reflective film is specifically designed for image rotation and inversion applications.
