DEVICE FOR COLLINEAR TRANSITION OF AXIS OF OPTICAL RADIATION Russian patent published in 2018 - IPC G02B27/10 G01B11/27 

FIELD: optics.

SUBSTANCE: device contains a mirror-prism system and a beamsplitter 4. Mirror-prism system contains a prism-roof 3 composed of separate elements with external reflecting surfaces and a mono-plate 1, which are united by an additional prism 2. Reflecting surfaces of the prism-roof face the beam splitter 4, made on the mono-plate 1. All the elements of the mirror-prism system form a hollow trihedral straight angle among themselves and are connected in series with each other in regions outside the optical radiation transmission zones. Composite prism-roof 3 is designed so that the part that contacts the additional prism 2 forms straight dihedral angles with each of its two reflecting surfaces.

EFFECT: improving the energy characteristics and improving the stability of the location of the radiation axes due to the connection of individual elements.
