Title: Lens holder
Inventor: HONDA TOSHIMASA
IPC: G02B7/02
Filed: 1982-08-16
Abstract: PURPOSE:To maintain lens performance and to obtain a lens system having high temperature resistance, by fixing a plastic lens with low temperature resistance in a lens frame without altering its shape, and correcting variation in refractive index with temperature. CONSTITUTION:The 1st lens 35 uses a normal glass lens and the 2nd lens 30 uses a plastic lens. The 1st lens 35 abuts on a 1st-lens barrel joining part 33 by being fittied in a 1st-lens fitting part 34, and is then fixed to the lens frame 31 by screwing a presser ring 32 into the lens frame 31 while threadably engaging a screw part 21 cut in the outer circumferential surface of the 1st-lens presser ring 32 with the 1st-lens frame screw part 28 cut in the inner circumferential surface of the lens frame 31. When the whole of the optical system is exposed to a high-temperature (or low-temperature) atmosphere after the optical system is assembled in a holder at room temperature, the 2nd plastic lens 30 varies in refractive index and a lens body 38 varies in radius of curvature (shape change) to cause the focus movement of the optical system.

Title: Color solid-state image sensor
Inventor: MIYAGAWA YASUMI
IPC: H01L31/0216
Filed: 1984-07-10
Abstract: PURPOSE:To remove the generation of quasi-signals by flare, a method wherein materials which absorb light are painted on the whole end surface of a glass base plate which forms a color filter arrey, and the light paths of a flare component which generate quasi-signals are intercepted. CONSTITUTION:The filter arrey is composed of the glass base plate 24, a solid- state image sensor 17, adhesive 21 and a color filter. In the glass base plate 24, materials which absorb light on the whole end surface, for instance, oily black paint is painted.

Incident light is refracted maintaining the angle theta1<theta2 according to the refractive index and arrives to the C point, and incident light is reflected maintaining the angle of theta3=theta4 and arrives to the G point. Since materials which absorb light are painted at the G point, the incident light is absorbed at the G point, the flare components will not arrive to the light receiving surface.
