Embodiment 1
[0042] See attached figure 1 , is the spectral calibration device proposed by the present invention, mainly composed of three parts, 101 is a uniform lighting panel, 102 is an optical fiber, and 103 is an excitation light source module.
[0043] The structure of the lighting panel is as figure 2 As shown, the lower layer is a light guide plate, which is composed of a light inlet 1011A, a light guide strip 1011B, and a light uniform plate 1011C. The bottom surface of 1011C is a tetrahedral microstructure, and the prism plate 1012 is placed on the top of the uniform light plate 1011C. The light inlet 1011A guides the light transmitted by the optical fiber into the light guide strip 1011B; the light guide strip 1011B is used to reflect the light entering from 1011A to the light uniform plate 1011C. In order to improve the utilization rate of light, the side of the light guide strip is made with a certain inclination angle , and coated with a wide-band high-reflection film; the...
