SOLAR RADIATION SIMULATOR Russian patent published in 2018 - IPC B64G7/00 G01J1/08 F21V13/04 

FIELD: physics.

SUBSTANCE: simulator contains an arc light source around which the same channels are evenly set, each of which contains a condenser with an aperture diaphragm, a mirror set at an angle to the optical axis, a field diaphragm, and a collimating lens. The axis of the arc light source is located parallel to the optical axis of the collimating lens. The following relations are performed: D_c≤D_m.m.-D_con.m.; Δy_con.max.≥d_f.d., where D_c - the diameter of the collimating lens; D_m.m., D_con.m. - the diameters of the main and secondary mirrors of the test mirror-lens objective; N_ch - the number of channels in the simulator; Δy_con.max - the value of the transverse spherical aberration of the condenser at the maximum value of the aperture diaphragm; d_f.d. - the diameter of the field diaphragm.

EFFECT: reduction of the diameter of the collimating lens while maintaining a uniform brightness distribution over the field of the test lens, the possibility of measuring large-sized mirror-lens objectives.
