Reference optical prism ENSO-7

H-K9Lcubic

Its adjacent faces is 2~5 seconds, and there are 3-5 adjacent faces AR coated and cross reticle The cubic reference prism is a regular hexahedron, and the angle tolerance between its adjacent faces is 2~5 seconds, and there are 3-5 adjacent faces AR coated and cross reticle. In the development process of the spacecraft, the cubic mirror coordinate system can be constructed by directly measuring the normal of the cubic reference prism reflection surface with the electronic theodolite, and it can represent the spatial position of the product.
