BK7/fused silica Fingerprint scanner Right Angle Prism
Right Angle Prisms are the most popular of all prisms. They are used to deviate a beam 90° when used as shown or 180° when beam enters normal to the hypotenuse. Typical applications are: telescope diagonals, range finders, periscopes, cameras, bore sights, cube beam splitters,total internal reflectors, hypotenuse face reflectors, retro reflectors etc.
A: To deviate the light path by 90° or 180°.
B: Used in Telescope, Periscope, Microscopy, Medical Instrument and other optical system.
