IPC: G03B7/099
Filed: 1990-07-17
Abstract: PURPOSE:To accurately measure the brightness of an object by deforming a condenser lens so that a focal distance may be varied and making the light receiving angle of a photodetector variable. CONSTITUTION:By rotating a clamp ring 7 in a state where it screws on a holding part main body 6, the inside diameter of the holding part main body 6 is shortened and the curvature and the thickness of the condenser lens 5 held by the holding part main body 6 can be varied. Consequently, for example, the condenser lens 5 is deformed by the lens holding part 6 according to a zooming magnification and photographing distance. For example, in the case that the zooming magnification is increased, the condenser lens 5 is pressed from a periphery so as to vary the curvature of the condenser lens 5 and make the focal distance short, so that the light receiving angle of the photodetector 2 is narrowed and set at the light receiving angle in which reflected light from the object limited in a photographing area can be received. Thus, the photometry of the brightness of the object is accuratly performed.
