卡尔·蔡司公司最近为其生产的实验室用常规显微镜和体视显微镜配置了全自动35mm的MC80照相机,以供显微摄影之用。这种相机通过一只投射透镜把显微镜的图象直接传递到胶片平面。在观察目镜上标示的有效图象的边框实际上包括了整个视场。它的曝光控制有三种功能:一是带有明、暗视场校正的自动曝光,在ISO100/21°情况下,自动曝光的范围可复盖1/125秒～250秒;二是时
Carl Zeiss recently deployed a fully automatic 35mm MC80 camera to its production lab with a conventional microscope and stereomicroscope for photomicrography. The camera transmits the image of the microscope directly to the film plane through a projection lens. The border of the valid image marked on the observation eyepiece actually includes the entire field of view. Its exposure control has three functions: First, with bright, dark field correction of automatic exposure, in the case of ISO100 / 21 °, the scope of automatic exposure can be covered 1/125 seconds ~ 250 seconds; the second is when
