The spectrodividing photometric head is used in devices for the automation of agrotechnical technological processes. It is more stable in respect of climatic and soil conditions and is more selective. It consists of an optical part made of multilayer interference filters and dichroic elements dividing the luminous flux into two or more channels in the range from 610 to 720 nm 10 and from 720 to 800 nm 10 in case of two channels. The photoreceivers are silicon diodes operating at close velocities of photogeneration and electrical modes.
