A new kind of hard X-ray / gamma-ray optic is proposed. This optics may be useful for collecting primary X-rays or gammarays from a point source and direct secondary hard X-rays into a given direction. The main element of the proposed optic is a multichannel collimator, which is a glass poly-capillary tube. Incident gamma-rays or hard X-rays with energy E from a point source cross the channel walls of the collimator at a given angle to channel axis and produce secondary Comptonscattered hard X-rays with energy E₁ < E. A small portion of the secondary, Compton-scattered hard X-rays, which are emitted in parallel to the center axis of each channel, transmit through the collimator without absorption, forming a hard Xray beam.
