Description
Technical Field
The disclosure generally relates to the technical field of spacecraft ultraviolet irradiation tests, in particular to a condensing lens and an ultraviolet irradiation device for a solar simulator.
Background
In the field of aerospace, in order to ensure that a spacecraft can normally work in a space environment, a series of space environment simulation tests are required to be carried out before launching. Among them, the ultraviolet irradiation test is one of the key test items. In a vacuum environment, the earth atmosphere is not protected, and when the spacecraft is exposed to ultraviolet radiation for a long time, many parts can be damaged, deformed, aged and the like, so that the operation of the spacecraft is influenced. In order to accurately simulate the space ultraviolet irradiation environment, corresponding simulation equipment, namely an ultraviolet irradiation source, is needed.
At present, an integrating rod type ultraviolet radiation source widely used generally uses an ellipsoidal condenser lens through a reflective light path, the light source is placed at one focus of an ellipsoid where a reflecting surface is located, light emitted by the light source is converged to another focus after being reflected, meanwhile, the center of an end face at one end of the integrating rod is placed at the other focus, so that the converged light is uniformly transmitted to the other end face through the integrating rod, and then the converged light passes through an optical imaging system to finally emit light meeting the requirements of the ultraviolet radiation source. For accelerated aging experiments, the ultraviolet radiation source usually provides irradiation with several times of solar constant, and the imaging lens group usually forms a real image with multiple times of magnification, so that the energy density at the integrating rod is many times higher. Therefore, by adopting the ellipsoidal condenser, the center of the incident end of the integrating rod is the focus of all energy convergence, and the energy is too concentrated, so that the end face of the integrating rod is easily damaged. In practical use, the end face of the integrator rod is damaged by the focused light due to tiny dust or flaws, so that the light transmission effect is influenced, and the service life of equipment is shortened. Therefore, we propose a condenser lens and an ultraviolet irradiation device for a solar simulator, which are used for solving the problems that the distribution of the focusing light spots is concentrated, the energy density borne by the central area of the end surface of the integrating rod is extremely high, the possibility of damage to the end surface of the integrating rod is greatly increased, if the interference of fine particles exists on the surface of the end surface, the end surface of the integrating rod is extremely easy to burn and invade by energy, the output power of a subsequent ultraviolet irradiation source is reduced, and the performance is rapidly reduced.
