Luminmaire Integrating Sphere with Diffuse Reflection 0.93 and Tube Support
The integrating sphere is a hollow sphere with a white diffuse reflective material on its inner wall. One or more apertures are formed in the wall of the ball to serve as an entrance aperture and a receiving aperture for the placement of the light receiving device. The inner wall of the integrating sphere should be a good spherical surface, and it is usually required that the deviation from the ideal spherical surface should be no more than 0.2% of the inner diameter. The inner wall of the ball is coated with an ideal diffuse reflection material, that is, a material having a diffuse reflection coefficient close to one. A commonly used material is magnesium oxide or barium sulfate, which is uniformly mixed with a gum binder and sprayed on the inner wall. Thus, the light entering the integrating sphere is reflected multiple times by the inner wall coating to form a uniform illuminance on the inner wall. In order to achieve high measurement accuracy, the aperture ratio of the integrating sphere should be as small as possible.
