Abstract

908,319. Viewing-apparatus. JASON, N. V. Feb. 24, 1961 [Feb. 25, 1960], No. 6889/61. Class 97 (1). In a binocular viewer for viewing a picture, which viewer comprises a central isosceles prism arranged so that rays of light from the picture first pass through the base of the prism which is normal to the viewer axis, the apex angle of the prism is such that the rays are totally innally reflected off each of the equal faces and then pass out of the prism through the other equal face so as to be normal or nearly normal to the other face, reflecting means being arranged to direct the two resultant rays through a pair of oculars arranged in stereoscopic manner. As shown, a binocular viewer for viewing a transparency supported at D comprises a central prism P, two mirrors M 1 , M 2 and two oculars, the arrangement being such that light received by the two eyes 0 1 , 0 2 follows the paths indicated. The oculars may be adjustable for focusing and for interpupillary spacing and the transparency may be moved towards and away from the prism P for adjusting the convergence of the beams incident on the eyes. In modifications (Figs. 3- 5, not shown) prisms may replace the mirrors M 1 and M 2 and an objective lens may be inserted between the transparency and the prism P.
