Device for controlling transmittance of optical apparatus with light conducting

摘要

the invention relates to a device for transmittanzkontrolle in optical devices with lichtleitmedien, especially in endoskopieeinrichtungen, with means for recording the illumination and conversion into an electrical magnitude, and an indicating device for the visualization of value of the electrical quantity.in a device of this kind a fault location throughout the lichtleitenden system with light source and lens clearly, quickly and constructively simple and virtually fail safe resources is erfindungsgemu00e4u00df suggested that as a means of measuring the bele uchtungsstu00e4rke a light sensor (13) is provided.what a unilaterally open shell (10) is arranged that adapter (20, 30, 40, 50) are provided, which in the pod (10) or steckbar, and that the dimensions of the sleeve (10) and the adapter (20, 30, 40, 50) are chosen so steckbereich that, in a spielpassung part of a gleitsitzes shows that casing (10) and adapter (20, 30, 40,50) with defined distanzmitteln (11, 31, 41, 51) are provided.
