Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] Such as figure 1 As shown, a multi-mode low-coherence scattering spectrometer is provided with a white light source 1, the white light source 1 adopts a xenon lamp light source, and emits white light with high intensity and low coherence. The white light emitted by the white light source 1 is collimated through the collimation optical path, which is composed of the condenser lens 2, the first lens 3, the first diaphragm 4, the second lens 5 and the second diaphragm 7 in sequence, after collimation The divergence angle of the incident light is 0.3°~0.5°, 0.4° is the best, and the diameter is as low as 2mm.
[0020] A polarizing plate 6 is arranged between the second lens 5 and the second aperture 7, and the linearly polarized light after collimation and polarization is incident on the mirror 8, and the reflected light of the mi...
