DEVICE FOR PRECISION ROTATION OF OPTICAL ELEMENTS Russian patent published in 2009 - IPC G02B7/00 G02B27/62 G12B5/00 

FIELD: physics.

SUBSTANCE: invention concerns area of optical instrument making and is intended for alignment of optical elements in optical systems where it is important to turn optical elements precisely with the minimum deflexion of their axis of rotation. The invention is directed on increase of optical element rotation accuracy. This technical result is provided because the device of precision rotation of optical elements has the basic rings with preload setting located between the underplate and the platform, forming surfaces of the contact electrode for the rolling elements in the basic assembly. According to the invention, position of the basic rings is corrected at the expense of additional adjustment that allows achieving moving of the rolling elements in one plane.

EFFECT: use of such adjustment allows reducing angular deflexion of a platform rotation axis and, accordingly, an axis of the optical element located on it to size less than 2 seconds of angle.
