摘要：

The limits of applicability of geometrical optical methods of calculating diffractive optical elements for terahertz radiation are determined. Use of the method of hot pressing in vacuum chambers to produce polymer transmissive diffractive elements for controlling terahertz radiation is considered. The effect of radiation absorption on the focal spot size and the radiation resistance of the elements are estimated. Experimental study of the optical characteristics of diffraction lenses fabricated in polypropylene revealed 17 percent differences from the diffraction limit.
