Avantier Inc.
Amici Prism Manufacture of Amici Prisms. When an amici roof prism is in use light will enter the prism through a short face and hit the reflecting surface of one of the roof faces. The light will then be reflected off the other roof face and exit the prism through the second short face. Because of this, the roof angle of an Amici roof prism must be highly precise; just four arc seconds deviation from a perfect right angle will result in double images. Careful craftsmanship and thorough testing are required... (read more) -

MOK Optics Co., Ltd.
Optical Prism Wholesale Corner Cube Prism Key Features And Advantages Of Corner Cube Prisms. Universal Reflection (180 Return). The most defining feature of a corner cube prism is its ability to reflect light back to its source at a 180 angle, independent of the incident angle. This is achieved through a specific geometry, where the prism is composed of three mutually perpendicular reflective surfaces that redirect incoming light to follow a precise path back along the same direction. High-Precision Retro-Reflection. The geometry... (read more)Browse Optical Prisms Datasheets for MOK Optics Co., Ltd. -
