Description

Technical Field

[0001] The utility model relates to the technical field of integrating spheres, in particular to a fixing device for an integrating sphere. Background Art

[0002] An integrating sphere is a hollow sphere with its inner wall coated with a white diffuse reflection material, also known as a photometric sphere, a luminous flux sphere, etc. One or several window holes are opened on the sphere wall, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface. Generally, it is required that the deviation from the ideal spherical surface should not be greater than 0.2% of the inner diameter. The inner wall of the sphere is coated with an ideal diffuse reflection material, that is, a material with a diffuse reflection coefficient close to 1. Commonly used materials are magnesium oxide or barium sulfate. After mixing it evenly with a colloidal binder, it is sprayed on the inner wall. The spectral reflectance of the magnesium oxide coating within the visible light spectrum range is above 99%. In this way, the light entering the integrating sphere is reflected multiple times by the inner wall coating, forming a uniform illuminance on the inner wall. To obtain a higher measurement accuracy, the opening ratio of the integrating sphere should be as small as possible. The opening ratio is defined as the ratio of the spherical area at the opening of the integrating sphere to the entire inner wall area of the sphere. The integrating sphere fixing device is a structure used to fixedly support the integrating sphere. With the progress of technology, people have higher requirements for the fixing device of the integrating sphere. Most of the existing integrating sphere fixing devices can only fixedly support the integrating sphere and cannot automatically control the opening and closing of the integrating sphere. The degree of automation is low, and manual pushing and pulling are required every time the integrating sphere is opened and closed, which is inconvenient to use;

[0003] There is a new type of integrating sphere fixing device CN208366361U, which includes an integrating sphere, a fixing frame and a supporting base. The integrating sphere is divided into left and right hemispheres. The first support plate and the second support plate are respectively connected under the two hemispheres. The first support plate is welded to the fixing frame. A connecting sleeve is provided between the first support plate and the fixing frame. The connecting sleeve is perpendicular to the first support plate. A through hole is provided in the connecting sleeve. The bottom of the second support plate is connected with a sliding plate. Slide rail grooves are provided on both sides of the sliding plate. Slide grooves are provided on the inner side wall of the fixing frame. Both sides of the sliding plate are embedded in the slide grooves. A lead screw is provided in the through hole. One end of the lead screw passes through the connecting sleeve and the first support plate and is perpendicularly welded to the second support plate, and the other end is connected with an electric push rod. A plurality of supporting bases are provided at the bottom of the fixing frame. When it is applied, it can automatically control the opening and closing of the integrating sphere, saving the trouble of manually pushing and pulling the integrating sphere for opening and closing, and is convenient to use;

[0004] However, when the existing fixing device is in use, it is not convenient for maintenance and replacement after long-term use and wear. At the same time, it cannot fix integrating spheres of different sizes. To solve the above problems, a fixing device for an integrating sphere is proposed. Summary of the Utility Model
