Description

Technical Field

[0001] The present invention relates to the technical field of light source detection, and in particular to a multi-purpose fixture capable of supporting FA camera and telecentric lens detection. Background Art

[0002] To detect the illuminance and wavelength of multi-spectral ring light, and to take pictures of color cards with cameras, two experimental stands are currently used. A steel ruler is used to adjust the required detection height of the light source and the camera in advance. After taking pictures of the color card, the light source needs to be taken to another experimental stand with a handheld illuminance meter to measure the illuminance value of the light source. The operation is very cumbersome. Every time a light source is changed, it is necessary to rely on the human eye to align the center points of the color card and the illuminance meter. The test accuracy cannot be guaranteed. In addition, the size of the fixed light source side of the experimental stand needs to be adjusted every time a light source is changed. When switching the FA camera and the telecentric lens, the center and height values ​​need to be realigned. The operation is cumbersome, resulting in low efficiency and accuracy during testing.
