引言摄象管的重要发展方向之一是使其光谱响应范围向红外和紫外扩展,为人们能在更宽的光谱范围内观察和研究各种现象提供重要条件。适用于微弱紫外光和低照度电视摄象系统的宽光谱SF-1401型摄象管已经研制成功,并已通过部级定型鉴定。该管属于硅增强靶(SI-T)摄象管,输入窗面板采用JGS_1远紫外光学石英,其紫外透过率很高,在石英面板的内表面,制作了多碱S-20型光电阴极,在此条件下,光谱响应范围可达1800-7500埃,在波长3300埃处其幅射灵敏度达到30毫安/瓦以上,这就使该管具有优良的紫外性能,以及宽光谱
Introduction One of the important development directions of video tube is to extend its spectral response range to infrared and ultraviolet, which provides important conditions for people to observe and study various phenomena in a wider spectral range. The wide-spectrum SF-1401 imaging tube for weak UV and low-light television camera systems has been developed and has passed ministry-level qualification. The tube is a silicon enhanced target (SI-T) imaging tube, the input window panel using JGS_1 far UV quartz, the UV transmittance is high, the inner surface of the quartz panel, produced a multi-base S-20 photocathode , In this condition, the spectral response range up to 1800-7500 angstroms, at a wavelength of 3300 angstroms at its radiation sensitivity of 30 mA / watts or more, which makes the tube has excellent UV performance, and a wide spectrum
