Dove Prism

We are offering dove prism.
Dove prism is used to turn imaging in some kinds of optics and mechanism system. When the prism circumvolve, the image circumvolve at twice angular velocity compared the prism. The ray which come into the prism must be parallel or vertical, because the length of the prism is four to five times than the height. The bevel of the dove prism is the maximal surface. Dove prism usually be used in total internal reflection mode, the bevel always do not plating, and the cleanliness of the surface is very important.
