Abstract

PURPOSE:To adjust the aberration of a lens, by buckling a transparent plastic plate forming the curved surface of the lens to vary the curved surface of the lens. CONSTITUTION:A slide member 7 fitted to a channel-shaped groove 6 of a left plate 2 is moved in parallel the direction of an arrow by the rotation of screw rods 13 and 14 connected directly to a crank 12. Transversal sections of life and right end faces of transparent acrylic plates 8 and 9 1.5mm. thick which are fitted to two parallel semicircular small grooves 10 and 11 of the slide member 7 are semicircular curved faces. The member 7 and acrylic plates 8 and 9 are sealed by sealing members 18 and 19, jwhich consist of an elastic silicone adhesive and can be deformed, so that a transparent silicone oil 20 is flowed out. Further, upper and lower ends of acryl plates 8 and 9 are sealed by elastic sheets 21 and 22, and the transparent silicone oil 20 is charged from a hole 23 of an upper plate 4.
