Standard optical device for color television camera
专利汇可以提供Standard optical device for color television camera专利检索，专利查询，专利分析的服务。并且PURPOSE:To ensure a simple and stable control for the titled standard optical device, by combining this optical device with a main optical system. CONSTITUTION:The light passing through a main optical system 10 produces nataurally a color aberration distortion through a field lens group 11, a relay lens group 14 and a color separating optical system 16 and has different positions of image formation when it is separated into red, green and blue colors. The color aberratioh is compensated by the groups 11 and 14. The luminous flux delivered from a standard light source 21 receives a control of color temperature through a compensating filter 22 and is condensed by a condenser lens to form an image temporarily at the position of a chart frame 24. This formed image passes through a field lens group 25 and is reflected by a fixed mirror 26 and an optical path switch mirror 27 to be fed to a fixed mirror 12. Thereafter the image is converted into electric signals of three colors by an image pickup element and after passing through the same optical path as the system 10. In such way, it is possible even for an unskilled operator to control a TV camera to a standard state in a comparatively simple way.，下面是Standard optical device for color television camera专利的具体信息内容。
