Description
Technical field
The present invention relates to the optical design technical field, be specifically related to a kind of solar simulator optical system.
Background technology
Solar simulator is a kind of test or the targeting device in lab simulation sunlight irradiation characteristic under different air quality conditions.The development in Solar simulation technology field and Chinese Space the reach of science are closely related.Solar simulator has become in the Chinese Space science important component part of carrying out space environment simulation test research on ground.Solar simulator is used for the ground environment simulated test of spacecraft more, is the chief component of space environment simulation equipment, for spacecraft provides that be complementary with the solar spectrum distribution, uniform, the stable light irradiation of collimation.
In other respects, the for example detection of electrooptical device solar cell in the solar photovoltaic scientific and engineering is particularly to a kind of detection that can receive the high-energy solar cell.Lab simulation solar spectrum irradiation in the remote sensing technology is studied development of plants and is cultivated fine seed strains or the like in the bioscience, is all using solar simulator.Yet the application of different places is different to the requirement of sunlight irradiation intensity, and therefore the structural requirement to the solar simulator optical system also is distinguishing.
With the most approaching prior art of the present invention be the paper that Changchun Institute of Optics, Fine Mechanics and Physics, CAS delivers; Name is called to be mentioned in " design of high power concentrator solar simulator "; Its structure is as shown in Figure 1, comprises xenon source 1, ellipsoid condenser 2, AM1.5 spectral filter 3 and light integrator assembly 4.Wherein, light integrator assembly 4 is the internal reflection taper cube of a hollow out, and its little openend is the effective irradiation face for the light beam output.The concrete structure relation is: xenon source 1 is positioned at first along of ellipsoid condenser 2; AM1.5 spectral filter 3 becomes 15 degree angles with the optical axis of ellipsoid condenser 2; Can be arranged near ellipsoid condenser 2 second focal planes; Light integrator assembly 4 is the internal reflection taper cube of a hollow out, and its big opening is positioned near second focal plane of ellipsoid condenser 2.The light radiant flux that xenon source 1 sends converges through 2 reflections of ellipsoid condenser and with the wrapping angle that designs, and projects on second focal plane of ellipsoid condenser 2, forms an irradiation profile in a big way; This in a big way converging beam to get into light integrator 4 be in the internal reflection taper cube of a hollow out; Through the repeatedly reflection on portion's reflecting surface within it, form comparatively evenly and the beam irradiation face with lambert's volume property of higher-energy in light integrator 4 little openend exits.
The subject matter that this optical system exists is: what the even photosystem of high power concentrator solar simulator was that the light integrator assembly adopts usually is the cube taper integrator of hollow out.It mainly is through the focused ray repeatedly reflection of portion within it, forms uniform higher-energy irradiation face being close to the exit.Just because of evenly the irradiation face can only be close to the integrator outlet, this system that makes does not have enough operating spaces when test specimen is tested, to the very inconvenience that is installed of test specimen.On the other hand, because focused beam is more at its integrator internal reflection number of times, the effective light energy reduction and the distribution of its uniformity that converge to the integrator exit have certain limitation, and have formed not the collimated light beam irradiation face with certain angle of collimation.
Summary of the invention
The present invention is the cube taper integrator of hollow out for what solve existing high power concentrator solar simulator optical system employing; Cause that system operating space to sample test the time is little, inconvenience is installed; Simultaneously because focused beam is more at its integrator internal reflection number of times; The effective light energy reduction and the distribution of its uniformity that converge to the integrator exit have limitation; And can not form the problem of collimated light beam irradiation face, a kind of high power concentrator collimation-type solar simulator optical system is provided with certain angle of collimation.
A kind of high power concentrator collimation-type solar simulator optical system; This system comprises xenon source, ellipsoid condenser, AM1.5 spectral filter and light integrator assembly; It also comprises collimator objective; Said xenon source, ellipsoid condenser, AM1.5 spectral filter, light integrator assembly and collimator objective are placed with optical axis successively, and said xenon source is positioned at first along of ellipsoid condenser, and the AM1.5 spectral filter becomes 15 degree angles with the optical axis of ellipsoid condenser; Said light integrator assembly is positioned at second along of ellipsoid condenser; Said light integrator assembly comprises optical cement plate and a plurality of regular hexagon element lens, and said a plurality of regular hexagon element lens are pressed the regularly arranged two groups of lens of on the optical cement plate, forming, and said two groups of lens are installed with optical axis on the contrary.
Operation principle of the present invention: the light radiant flux that xenon source of the present invention sends, converge through the reflection of ellipsoid condenser and with the wrapping angle that designs, project on second focal plane of ellipsoid condenser, form an irradiation profile in a big way; This irradiation profile in a big way is imaged onto the infinity via the light integrator assembly; Form an irradiation range uniformly; Again through collimator objective with certain beam collimation angular projection to the back focal plane of collimator objective, forms uniform irradiation face, i.e. an effective irradiation face.Described light integrator assembly adopts symmetrical expression element lens array; The formed optical channel of field lens and projection lens will converge to the irradiation profile symmetry division on second focal plane through the ellipsoid condenser, form the irradiation profile that is imaged on the infinity comparatively uniformly.Two group element lens arras at infinity form an irradiation face that is superimposed.This irradiation face is effective irradiation face place being imaged on through collimator objective on its back focal plane.
Good effect of the present invention: optical system of the present invention forms high-energy (2000 solar constants) and the equally distributed effective irradiation face with certain angle of collimation; Between described collimator objective and the effective irradiation face certain distance is arranged, but have certain operating space; One, the irradiation level on the raising effective irradiation face; Two, the irradiation level uniformity on the raising effective irradiation face; Three, form collimated light beam with certain angle of collimation.
