Prism |

| An
incident beam can be deviated by 90 degree without inverting or reversing
through a Penta prism. Penta prism has five sides, four of them polished.
Two reflective sides are coated with metal or dielectric HR coating and
these two sides can be blackened. The deviation angle of 90deg will not
be changed if the penta prism is slightly adjusted, this will be convenient
to install it. It is widely used in laser level, alignment and optical tooling.The
reflecting surfaces of this prism must be coated with a metallic or dielectric
reflective coating. |
