OFF-AXIS SOLAR SIMULATOR OF THERMAL VACUUM CHAMBER Russian patent published in 2012 - IPC G01J1/08 B64G7/00 

FIELD: physics.

SUBSTANCE: simulator has an input illuminator which is tightly built into the housing of the thermal vacuum chamber, a parabolic collimating reflector for reflecting the simulated solar radiation onto the test object lying in the thermal vacuum chamber, lamps - solar radiation sources, lying outside the thermal vacuum chamber. The illuminator is in form of a biconcave lens. The solar radiation sources are lamps with ellipsoidal reflectors and auxiliary spherical mirrors for returning some of the radiation which has not fallen on the surface of the reflector to the reflector. Between the parabolic collimating reflector and the biconcave lens on the path of light flux there is a mirror mixer which is in form of convex mirror lenses uniformly arranged in a plane and touching each other by their faces, said mirror lenses having square profiles for reflecting, mixing and increasing light flux to the size of the parabolic collimating reflector.

EFFECT: high efficiency of the solar simulator and uniformity of illuminating the surface of the test object.
