Dove prism is a prism by the HWDove invention. It was formed in half the ordinary rectangular prism, when the light parallel to the direction of the slope along with the injection prism, and after internal reflection by the inclined plane, along with the incident direction parallel to the direction of the injection; then turned around as the prism in a certain light angle, the image will turn a double angle. Dove prism must be used for parallel optical applications.
