Vidikon LI484ya-1, vidikon LI484S-1 (LI484ya-1, LI-484S-1, LI484ya-1, LI484S-1)
Desined TV device with a photodiode okisnesvintsovoy mishenyyu, magnetic focusing and deflection of the beam, an additional illumination of the target and the diode illuminator designed to convert light images into electrical signals in the transmission chambers of technical training: LI484ya-1 - for the luminance channel of transmission of color cameras, as well as for black-and-white cameras; LI484S-1 - for blue colored transmitting cameras.

 

 

    Vidikon LI484ya-1, vidikon LI484S-1 - transmit television devices with okisnesvintsovoy photodiode mishenyo, magnetic focusing and deflection of the beam, an additional illumination of the target and the diode illuminator designed to convert light images into electrical signals in the transmission chambers of technical training: LI484ya-1 - for transmitting the luminance channel of color cameras, as well as for black and white cameras; LI484S-1 - for transmitting blue color channel chambers.

 

 

Additional illumination of the target is carried out using the fiber inside the vidicon from an external light source located in the power panel vidicon. Additional illumination of the target reduces the lag in transmission facilities to low-light conditions.
Spotlight diode reduces inertia.
