Abstract (English):
The article proved that the highest concentration of reflected rays from the surface of the reflector is located along the quasifocal line. The quasifocal line belongs to the caustic surface of the congruence of reflected rays. The parameters of the shape and position of the quasifocal lines are described by equations. Computer visualization of reflecting surfaces, congruences of reflected rays and their caustics, quasifocal lines and maps of isolines of local concentrations on the surface of the receiver of reflected rays are presented.

Keywords:
quasifocal line, congruence of reflected rays, caustic surface, map of isolines of local concentrations
