High-concentration collimating solar simulator optical system

Abstract

The invention discloses a high-concentration collimating solar simulator optical system, which relates to the technical field of optical design and is used for solving the problems of small operating space for sample test in a high-concentration solar simulator optical system, inconvenience in clamping and limit on uniform distribution of light caused by the adoption of a hollowed cubic conical integrator in the system. In the system, a xenon lamp light source is positioned at the first focal point of an ellipsoidal collecting mirror; an angle of 15 degrees is formed between an AM1.5 spectral filter plate and the optical axis of the ellipsoidal collecting mirror; an optical integrator assembly is positioned at the second focal point of the ellipsoidal collecting mirror, and comprises an optical cement plate and a plurality of regularly-hexagonal element lenses; the plurality of regularly-hexagonal element lenses are regularly arranged on the optical cement plate to constitute two groups of lenses; and the two groups of lenses are arranged coaxially and oppositely. By adopting the high-concentration collimating solar simulator optical system, the irradiance uniformity on an effective irradiation surface is increased effectively.

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. The development of solar simulation technology is closely related to the development of space science in my country. Solar simulators have become an important part of space environment simulation experiments on the ground in my country's space science. 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. [0003] In other aspects, such as the detection of photoelectric conversion device solar cells in solar photovoltaic science and ...

AI Technical Summary

Problems solved by technology

[0006] The present invention solves the problem that the existing high-magnification concentrating solar simulator optical system uses a hollowed-out cube-cone integrator, which results in a small operating space and inconvenient installation of the system when testing samples. At the same time, the focused beam is reflected inside the integrator. The number of times is high, the effective light energy converging to the exit of the integrator is reduced, and its uniformity distribution has limitations, and it cannot form a parallel beam irradiation surface with a certain collimation angle. It provides a high-magnification concentrating collimation solar system Simulator Optical System
