Optical system of high-energy and high-collimated angle solar simulator

Abstract

An optical system of a high-energy and high-collimated angle solar simulator relates to the technical field of optical design and solves the problems in an existing simulation optical system such as that radiation energy is greatly lost in front of an optical integrator, an irradiance degree of the solar simulator is generally only equal to 0.3 solar constant, and heat dispersion is poor at an ellipsoid collecting lens and the optical integrator. The optical system of the high-energy and high-collimated angle solar simulator comprises a conical-face collecting lens and a collimation diaphragm, wherein optical axes of the ellipsoid collecting lens and the conical-face collecting lens pass through the center of a reflection face of a plane mirror; an angle of 90 DEG is formed between the optical axis of the conical-face collecting lens and the optical axis of the ellipsoid collecting lens, and an optical integrator assembly, the collimation diaphragm and a collimation objective lens are placed in succession from left to right on the optical axis of the conical-face collecting lens; a projection lens in the optical integrator assembly is located around a front focus face of the collimation objective lens; the collimation diaphragm is located on the front focus face of the collimation objective lens; and a wing-shaped cooling fin is formed through processing on the outer surface of the conical-face collecting lens. The optical system disclosed by the invention minimizes energy lost at the optical integrator assembly.

Description

technical field [0001] The invention relates to the technical field of optical design, in particular to a solar simulator optical system. Background technique [0002] A solar simulator is a test or calibration device that simulates the characteristics of solar radiation under different air quality conditions indoors. Solar simulators are mostly used for ground environment simulation tests of space vehicles, and are the main components of space environment simulation equipment, providing spacecraft with uniform, collimated and stable light irradiation that matches the solar spectral distribution. In the spacecraft vacuum thermal environment test, the solar simulator is the most realistic and accurate heat flow simulation method. The application of the solar simulator can complete the spacecraft thermal balance test with high precision, especially for the thermal balance of the spacecraft with complex shape and complex thermal coupling relationship. The test must be done wit...
