Problems solved by technology

In order to obtain uniform illumination of multiple wavelengths, some use flat LED surface light panels to obtain light source information of different wavelengths. The light produced by this light source is not uniform, and some use hemispherical diffusers to gather light, but there is still no better. uniform effect, and there will be shadows during the experiment, which cannot provide good experimental requirements

Abstract

The invention discloses an LED light diffusion light-uniformizing system for multispectral imaging and a use method of the system. The system comprises a light uniformizing device with a curved surface reflection function; the light uniformizing device is of a hemispherical structure; a through hole is formed in the upper portion of the light uniformizing device; an annular metal sheet connected with the objective lens of an integrated microscope for a laboratory is arranged at the through hole; a PCB curved plate is arranged in the light uniformizing device; multi-wavelength LED light sourcesare evenly arranged on the PCB curved plate; and a control switch used for controlling the LED light sources is arranged at one side of the outer portion of the light uniformizing device. With the LED light diffusion light-uniformizing system for multispectral imaging of the invention adopted, the combined use of a conventional halogen lamp and an optical filter can be replaced. The system has the advantages of long service life and good lighting effect. According to the LED light diffusion light-uniformizing system for multispectral imaging and the use method of the system, LEDs with variouswavelengths are uniformly mixed so as to be used.

Description

technical field [0001] The invention belongs to the technical field of multispectral imaging, and in particular relates to an LED light diffusing and homogenizing system for multispectral imaging and an application method thereof. Background technique [0002] In the multi-spectral imaging lighting system, the combination of halogen lamps and filters is often used to obtain a single-wavelength light source. The disadvantage is that the range of use is narrow and the service life is short. LED light source has excellent monochromaticity, high photoelectric conversion, green environmental protection, long life, and stable beam. In view of these advantages, LED light source is widely used, such as machine vision and microscopic lighting. The design and improvement of multi-wavelength LED light source system is helpful to the improvement of multi-spectral imaging hardware system. [0003] At present, there is a demand for an LED light source system with multiple wavelengths and...
