Abstract
The utility model relates to the field of optical imaging, in particular to a multifunctional coherence instrument. A light source device of the multifunctional coherence instrument comprises a light source, a needle hole filter, a lens assembly and a grating rotating part which are positioned in the horizontal direction from left to right; and the lens mainly comprises a focusing lens, a front lens and a rear lens. The lights emitted from the light source form a divergent beam which has an origin positioned in a needle hole and propagates along the horizontal light axis after penetrating through the needle hole filter. The focusing lens converts the divergent beam into a convergent beam; all the convergent light points of multiple convergent beams illuminate the section of a sample and excite the section to reflect light. The reflected light of the sample is imaged on the plane through the front lens and the rear lens. A transmission ball lead screw is connected with a bearing seat by a bearing, and the lens assembly is fixed on the bearing seat. The lead screw is controlled to move by electricity, so that the lens on the bearing seat is driven to move horizontally, the effect of eliminating stray light of the coherence instrument is good and the coherent light source meeting the requirements of the visual field or resolution ratio can be provided.
