Design of High-temperature Tv Camera
高温电视摄像镜头设计

The designing method of high-temperature TV optical camera was discussed; the problem of the material which used in this case, the parameters and the direction pointing of the optical axis were analyzed. Three times imaging system has been used to realize the objective. By maintaining the little diameter of all lens in the system the whole system has been elongated. And the evaluation result of the designed system were showed, the outcome identified that the system can work well under large variety range of temperature, the idea which design this optical system could be adopted by other high temperature optical system.
