Abstract
Special scientific instruments on the base of electron-optical converters are created in laboratory of functional electronics at Vyatka State University. Their purpose is to detect ultra-weak fluorescence of biological objects, especially in infrared range. A good example is two-chamber electron-optical converter with electrostatic focusing 6ЕР21MG.
Its main technical specifications are the following:
- the range of maximal spectral sensitivity of photocathode - 400-1500 nm;
- effective coefficient of brightness increment - 10^4;
- diameter of photocathode active surface - 24 mm;
- the size of field on output screen - 18 mm;
- max voltage - 30 kV;
- resolution - 30 mkm.
