The integrating sphere device for generating multi-wavelength light source has the advantages that the temperature inside the integrating sphere can be controlled; the angles of the light sources ofdifferent wavelengths inside the integrating sphere can be adjusted; and the diffusion of the light sources can be static or dynamic, which helps to improve the generation efficiency of the multi-wavelength light sources.

Description

technical field [0001] The invention relates to the field of light radiation, in particular to an integrating sphere device for generating a multi-wavelength light source. Background technique [0002] The integrating sphere is a hollow sphere whose inner wall is coated with white diffuse reflection material. One or several windows are opened on the wall of the sphere, which are used as the light inlet hole and the receiving hole for placing the light receiving device. The inner wall of the sphere is coated with ideal diffuse reflection. In this way, the light entering the integrating sphere is reflected multiple times by the coating on the inner wall, forming a uniform illuminance on the inner wall. Many light sources with different wavelengths are set in the integrating sphere. Since the inner wall of the sphere is neutral and uniform diffuse reflection, for various The incident light of wavelength has the same diffuse reflectance, so that it can emit multi-wavelength li...

[0002] The integrating sphere is a hollow sphere whose inner wall is coated with white diffuse reflection material. One or several windows are opened on the wall of the sphere, which are used as the light inlet hole and the receiving hole for placing the light receiving device. The inner wall of the sphere is coated with ideal diffuse reflection. In this way, the light entering the integrating sphere is reflected multiple times by the coating on the inner wall, forming a uniform illuminance on the inner wall. Many light sources with different wavelengths are set in the integrating sphere. Since the inner wall of the sphere is neutral and uniform diffuse reflection, for various The incident light of wavelength has the same diffuse reflectance, so that it can emit multi-wavelength light source, but the current integrating sphere device generally does not have a temperature adjustment device, and the light will be affected by temperature, so it will affect the generation of multi-wavelength light. The efficiency and effect of the light source. Moreover, the light source inside the existing integrating sphere is generally fixed and cannot be adjusted, which will also have a certain impact on the generation of multi-wavelength light sources.
