在研制满帧非扫描全电子辐射热的变像管过成中,需用一个高质量的红外光学系统对它进行试验和评定,而大量生产的高速和在平的焦平面上具有高分瓣力的光学系统是不适用的。为此,用计算机重新进行设计或在为别的目的而用的光学系统基础上重新进行最佳化。现在设计的透镜系统包括三片镀多层增透膜的锗透镜和一片碘化铯透镜,工作在8～14微米,F/0.75,f′=100,约30毫米的平焦平面内最小分辨力当调制度为10%时是10对线/亳米,根据设计、制造和试验的数据证明,透镜系统是一个高质量系统。其缺点是由于透镜透过率降低导致测量的 T 数为0.997,而期望值是小于0.9。
In the development of a full frame non-scanning electron radiation heat of the variable tube over, the need to use a high-quality infrared optical system to test and assess it, and mass production of high-speed and flat in the focal plane with a high score Force optical system is not suitable. For this purpose, the computer is redesigned or the optical system used for other purposes is re-optimized. The lens system now being designed includes three germanium lenses coated with a multilayer antireflection coating and a cesium iodide lens that operates with minimum resolution in a flat focal plane of 8 to 14 microns, F / 0.75, f ’= 100, and about 30 mm Force is 10 lines per millimeter when modulation is 10%, and the data from the design, manufacture, and test proves that the lens system is a high quality system. The disadvantage is that the measured T-number is 0.997 due to the decrease in lens transmittance and the expected value is less than 0.9.
