The gold-plated hollow roof prism is composed of two right-angle prisms and a rectangular substrate, with the substrate material being K9. The Angle between the two inclined planes of the reflector is 90°. When the incident light is incident perpendicularly to the base surface, a 180° reflection can be achieved. The hollow roof prism can reflect the light incident from the outside onto the bevel of the prism. Different from a plane mirror, the reflected light remains parallel to the incident light, avoiding the influence of beam interference. It is more precise than manually adjusting two mirrors, with the return beam accuracy as low as 2 arc seconds.
In addition to the standard hollow roof ridge prism, other coatings and sizes can also be customized.
