OPTICAL CIRCUIT OF OPTIC-LASER CENTERING DEVICE Russian patent published in 2006 - IPC G01C1/02 G02B27/62 

FIELD: optical engineering.

SUBSTANCE: optical circuit of optic-laser centering device has eye-glass, mesh, objective, prism made for change in ray path by 90° and for get direct image in eye-glass. It also has laser module made for creation of narrow laser beam to radiate in visible spectrum range, light-splitting unit disposed between objective and prism. Optical coating is applied onto splitting face of light-splitting unit. Optical coating is made for reflection of light flux of laser beam and for transmission of visible image into eye-glass. Optical circuit can be used in geodetic devices during natural day and night time.

EFFECT: improved comfort at application.
