Patent ID: 12013286

Abstract:
A Raman spectroscopy probe and a Raman spectroscopy detection device are provided including an optical fiber module, and a magnifying lens group and a detection window sequentially arranged on an optical path thereof, wherein the optical fiber module includes an excitation fiber and parallel collection fibers surrounding a periphery thereof; the magnifying lens group includes sequentially-arranged convex lenses, the detection window is located near an object-distance position of a lens close to a detection end. A distance between two adjacent convex lenses is equal to a sum of former's image and latter's object distance. Focal lengths of the convex lenses in the magnifying lens group are f, and satisfy a ratio of the object distance to the image distance of n:1, and a length L of the magnifying lens group satisfies: wherein  N is a magnification, and m is a number of the convex lenses.
