OPTICAL BEAM SPLITTER IN FORM OF COMPOSITE DICHROIC PRISM Russian patent published in 2015 - IPC G02B5/04 G02B27/10 G01J3/14 

FIELD: physics, optics.

SUBSTANCE: invention relates to optical instrument-making and an optical beam splitter. The optical beam splitter is a composite dichroic prism and is made in form of several transparent prisms glued together. The transparent prisms have on one face at the gluing point a dichroic coating intended for reflecting different frequency components of incident radiation. The shape and mutual arrangement of the transparent prisms is selected based on the condition of intersection of glued planes at one point.

EFFECT: higher compactness of the structure.
