The invention relates to the making, in particular to optical-mechanical devices for the concentration of energy sources of energy, and can be used in microscopes, telescopes, fotocamera.Known as the hub of radiation, which is the task of concentrating radiation is solved through the use of a single curved mirror.The disadvantage of the invention is that the image is flat, and the energy density of radiation is not high enough.Closest to the claimed is a device for concentration of energy  which contains two concave mirrors in kind is prohibited axial hole, and on the inner surface of the hemispheres applied mirror coating.The disadvantage of this device is not a high energy density radiation received by him.The aim of the invention is to increase the energy density of the radiation source.The goal is achieved in that the mirror system gain and energy density of the radiation source containing two concave mirrors in the first and second hemispheres, and established the concave sides toward each other, and a second hemisphere is made of the axial hole, and the mirror was coated on the inner surfaces of the hemispheres, put a positive lens mounted on the optical axis before the first hemisphere in which the axial hole and the mirror element made in the form of two hemispheres, and established the internal surfaces to each other on the optical axis of the device for the first hemisphere, and in the hemispheres of the mirror element is made of the axial bore, the mirror element and the second hemisphere device mounted for movement on the optical axis of the device, and the internal and external surfaces of the hemispheres of the mirror element Nanase Kratovo passing a light beam in a limited volume of the mirror element, which leads to its accumulation, and increase the intensity of the output light flux, leading to the increased resolution.This result is ensured by the fact that in the known device entered the mirror element is a hollow body formed of two hemispheres, facing each other, an inner surface, which caused the mirror coating, with the axis of the chamber is provided through holes on the intake system before the first hemisphere posted positive lens; on the external surface of the hemispheres of the mirror element is also applied mirror coating.Thus, the mirror element is a hollow body with a metallic mirror coating on both sides and two axial holes. From this it follows that the working surfaces are the inner and outer surface of the mirror element.The mirror element is mounted using three calibration screws, ensuring its alignment.In Fig.1 shows a functional diagram of the system illustrating the principle of operation of the mirror element of Fig.2 diagram of the mirror element.Mirror si surfaces 3 and 4 and tricks 5, 6 accordingly, the mirror element 7 with mirror surfaces 8, 9 and axial holes 8, 9 and axial holes in the shape of circles 10, 11 along the Central axis of the system, calibration screws 12, the input and output apertures 13 and 14 of the system input positive lens 15.The system works as follows.A beam of light passing through the second positive lens 15 through the inlet 13, falls on the mirror element 7, whose working surfaces are both internal and external. Through the axial hole 10 of the beam enters the mirror element 7.Inside the mirror element 7 through the axial hole 10, the beam of light is reflected many times from the two inner mirror surfaces 9 of the hemispheres of the mirror element 7, is connected with the direct beam and exits through the axial hole 11 of the mirror element 7 in the form of a compressed beam of light.The input beam is reflected from the outer surface 8, is reflected in the hemisphere 1. Numerous reflections from the spheres 1 and 2, the light also accumulates in and out of the holes 14, reflected from the outer surface 8 of the mirror element 7.Thus, the flow of light at the output of the system consists of a compressed Potocka output system, the average on the periphery of the mirror surface 8 of the mirror element 7, and the lowest in the hemisphere 1. The image output system is inverted.Application device for a telescope or microscope increases their resolution. Mirror amplifying and energy density of the radiation source containing two concave mirrors in the first and second hemispheres, and established the concave sides toward each other, and a second hemisphere is made of the axial hole, and the mirror was coated on the inner surfaces of the hemispheres, characterized in that it introduced a positive lens mounted on the optical axis before the first hemisphere in which the axial hole and the mirror element made in the form of two hemispheres, and established the internal surfaces to each other on the optical axis of the device for the first hemisphere, and in the hemispheres of the mirror element is made of the axial bore, the mirror element and the second hemisphere device mounted for movement along the optical axis of the device, and the internal and external surfaces of the hemispheres of the mirror element applied mirror coating.
