Abstract

1,270,030. Remote observation apparatus. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 2, 1969 [July 10, 1968], No.33373/69. Heading G2J. An apparatus for the remote observation of objects has an objective 2 of variable focal length and an adjustable lens group 4 transmitting a parallel light beam to a fixed lens group 6, a first mirror system 16, 18 and a second mirror system 8 for deflecting a beam to an eye piece unit 10 also being provided. An image of the object is transmitted through glass window 104, mirror 106 and objective 2 on to the front focal plane of lens group 4 which passes the image through mirror 16, 18 lens group 6, either to binocular eye-piece 10 or to a photographic recording system 12 via movable mirror system 8. The remote adjustment of the lens elements of 2 and 4 is achieved by a system of toothed wheels and connecting rods attached to a set of manual control knobs adjacent the eye-piece unit 10. Alternatively an electric control system may be used. The apparatus comprises tubes 14, 3, 1 the latter being slidable on rollers 101 into a projecting tube 102 set in the wall 100 of a leak proof chamber e. g. a furnace or pressure or vacuum chamber, the window 104 and the flange 108 sealing the apparatus. The mirror 8, Fig. 12 (not shown), is pivotable on stand (88) via a spring and pivot arrangement by knob (97), two arms (98) and a stop (96) limiting the movement. The mirrors 16, 18 may be replaced by a single mirror.
