The Optical Penta Prism can deviate an incident beam without inverting or reversing to 90 degree. The deviation angle of 90 degree is independent of any rotation of the prism about axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Range Finding and Optical Tooling. The reflecting surfaces of the prism must be caoted with a metallic or dielectric coating. The standard Penta Prism reflecting surfaces are coated with aluminum or enhanced aluminum. Creator Optics ( CNCO ) is a manufacturer of customized optical penta prisms in China. The company can provide various penta prisms made from optical glass and crystals. The avaliable materials of optical penta prisms are as follows: BK7 and other optical catalog glass, UV and IR grade fused silica, synthetic sapphire monocrystal, etc.
