新研制的低输出电容、低余象硒砷碲摄象管的信号输出电容不到老式管的一半。光电导膜电容也有显著改进,只有老式管的2/3以下。这种改进能使广播用彩色摄象机的信噪比(S/N)及余象得到改善。此外,高电压工作时,该管的分辨率是老式管的1.5倍以上,可获得更为优质的广播图象(照片1略)。新型硒砷碲摄象管有18mmH9366和25mmH9369两种。尤其H9366,虽为18mm,但分辨率和25mm的老式管相同。
The newly developed low output capacitance, low residual signal selenium arsenic tellurium signal tube output capacitance of less than half the old tube. Photoconductive film capacitors have also been significantly improved, only 2/3 of the old tube below. This improvement can improve the S / N ratio and the afterimage of color video cameras for broadcast. In addition, high-voltage operation, the resolution of the tube is 1.5 times more than the old tube, you can get a better broadcast image (photo 1 omitted). New selenium, arsenic and tellurium imaging tube 18mmH9366 and 25mmH9369 two. In particular, H9366, although 18mm, but the same resolution and 25mm of the old tube.
