GENERAL-PURPOSE MULTIPLE-UNIT RADIATION POLARISER (GMRP) Russian patent published in 2008 - IPC F21V9/14 

FIELD: physics.

SUBSTANCE: polariser includes, at least, one radiation source, reflector, at least, one shaper that is radiation polariser containing spaced sensor lens system, orthogonal polarising radiation component split system and beam directivity former system, as well as system of spatially matching rotators of polarising radiation component. Lens systems are hollow with cavities having outflows at least to one inlet and one outlet fittings to pump optically transparent cooling agent. The polarising radiation component rotator system is based on liquid crystals of internal orientation. Its surfaces contain optically transparent electrodes. The system of polarising radiation component split system is based on birefringent substance with critical angle of internal reflection of one polarising radiation components, thus directors of birefringent substance are oriented in parallel to optical axis of reflector.

EFFECT: reception of packaged and production-friendly design.
