PROJEKTOR FOER FRAMSTAELLNING AV EN LJUSFLAECK AV POLARISERAT LJUS SAERSKILT FOER BIOSTIMULERING.

摘要

A projector for producing a uniformly illuminated remote light spot of polarised light which can be used for biostimulation. …The projector comprises a box-like housing (1) in which a metal halogen lamp (2) is arranged with upwardly directed diverging beams. A Fresnel lens (3) is arranged in an upper opening of the housing to direct the light beams in a parallel bundle towards a Brewster polariser (4) which is hingedly connected to the upper portion of the housing. …The polarised light reflected from the polariser propagates in a parallel bundle and the beam collimation is sufficiently correct for illumination from distances of up to 3 m.
