Embodiment Construction

[0016] The structure of the multi-light path near-ultraviolet radiation simulator of the present invention will be described in detail below with reference to the accompanying drawings, but this description is only exemplary and is not intended to limit the protection scope of the present invention.

[0017] refer to figure 1 , figure 1 It shows the multi-path near-ultraviolet radiation simulator of the present invention, which includes a xenon lamp 1, a condenser mirror 2, an integrator 3, a reflector 4, a telephoto lens 5, and a collimator mirror 6. The xenon lamp 1 set in the chamber 1 converges the light through the condenser 2 and then enters the chamber 2 through the opening hole on one side wall of the chamber. The other side wall of the chamber 2 is correspondingly provided with an integrator 3 and enters the chamber 2. The light in the light passes through the integrator 3 and then diverges and exits, and is incident on the reflector 4 on the hypotenuse of the isosce...

Abstract

A disclosed multi-light-path near-ultraviolet irradiation simulator comprises a xenon lamp, a condenser, an integrator, a long-focal-length lens and a collimating mirror; light emitted by the xenon lamp is converged by the condenser and passes through an opening at the sidewall of a chamber I and enters a chamber II, the integrator is arranged at the other sidewall of the chamber II, and light is uniformized by the integrator, is emitted in a divergent way, then meets a reflector at the hypotenuse of a right-angled-triangle chamber, then is reflected at 45 DEG and meets the long-focal-length lens, and is uniformly irradiated by the long-focal-length lens in a divergent way. The multi-light-path near-ultraviolet simulator has the advantages of large irradiation area, high irradiance and usage agility. Aiming at a test piece with the area less than an area with the diameter of 180 mm, a large-irradiance work module with collimation type 10 ultraviolet constant is employed for tests, test time is saved. Aiming at an integral or spliced test piece with the area close to an area with the diameter of 300 mm, a work module with 5 ultraviolet constant is employed, the irradiation scope is amplified and test efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet radiation simulation, and in particular relates to a simulator for carrying out ultraviolet radiation tests on sensitive materials, components and components. Background technique [0002] Usually, the ultraviolet radiation simulator is used to simulate the ultraviolet solar radiation in the range of 200nm to 400nm. Therefore, the UV radiation simulator has a wide range of applications. [0003] The multi-light path near-ultraviolet simulator is used by replacing the collimator lens and the telephoto lens to obtain collimated light or divergent light. It can reach 5 UV constants in the Φ300mm irradiation area and 10 UV constants in the Φ180mm range, realizing different radiation Switching within the range of irradiation area and irradiance, a single UV simulator achieves the purpose of multiple indicators and high performance. [0004] The traditional ultraviolet radiation simulation equipme...
