<p>The present invention is directed to optical systems for free space optical devices and communication technologies. Described free space optical systems are widespread in wireless data transmission with monochrome optical transmitters (semiconductor lasers) operating in one radiation wavelength as in transmitting, so in receiving optical channels with shared optical system for communication device. Offered optical device is developed as shared optical system (1) in whose output on its optical axis (9) the optical beamsplitter block (7) is placed and on the optical system (1) focal plane (F1) on its optical axis (9) the diaphragm (12) is placed. Behind the diaphragm (12), in parallel and coaxial to the optical system's (1) optical axis (9, the spherical aberration free chromatic component (16) is placed. Behind the component (16) on its optical axis (9) the communication device for each channel (accordingly 17, 18, 19) is provided with the communication sensor (accordingly 20, 21, 22) of optical mating system's input (accordingly 23, 24, 25). The offered optical system enables to unite numerous simultaneouly and independently operating optical communication channels in shared optical system with common optical axis having minimum optical noise level, as from adjacent optical channels, so from the outside radiation.</p> |
