FIELD: optical engineering.
SUBSTANCE: device has inlet 6 and outlet 8 ends connected by plurality of vacuumed or filed by other gas-like environment channels for transporting optical radiation. Extensions of outlet 7 and inlet 9 ends of channels beyond limits of input and output ends are directed in such a way, that in total they have shape of input and required output flows of optical radiation recognized by the device. One or two ends of device, excluding input and output apertures of channels, have non-transparent cover, or channels walls and environment between channels are non-transparent. If extensions of longitudinal axes of channels on the side of input and output ends cross in points placed on extension of longitudinal axis of device, it s capable of focusing divergent flow of optical radiation of quasi-dot source. If extensions of longitudinal axes of channels on the side of one of ends cross in a point placed on extension of device parallel axis, and extensions of longitudinal axes of channels on the side of another end are parallel to longitudinal axis of device, it transforms diverging flow of optical radiation of quasi-dot source into quasi-parallel.
EFFECT: separate transfer to output of radiation energy and respective optical information from different element of input flow formed by light source or lighted object.
