Abstract

The invention provides a Raman probe based on a fly's-eye lens. The Raman probe comprises an incident light source, a narrow-band optical filter and a dichroscope which are arranged in sequence; and also comprises a first collecting lens which is located at one side of the dichroscope in the light path direction, a second collecting lens which is located at the other side of the dichroscope, and an exit slit which is located at the other side of the dichroscope; and also comprises the fly's-eye lens which is located between the dichroscope and the first collecting lens and used for expanding the view field range and reducing the light energy density. According to the Raman probe, the fly's-eye lens is applied to homogenize light beams, the view field range is effectively expanded, and the transmitted light energy density is reduced. In actual use, the risk of igniting or detonating a dark sensitive substance sample for detection can be effectively reduced, and the function of detecting a non-uniform mixture sample is expanded.

Description

technical field [0001] The invention relates to the technical field of Raman detection, in particular to a Raman probe based on a fly-eye lens. Background technique [0002] As a "fingerprint" scattering spectrum of an object, Raman spectroscopy has the characteristics of high analysis efficiency, less sample consumption, and strong applicability. It can reflect the molecular structure of substances and provide rich information on the structure of substances. Therefore, Raman spectrometers are widely used in scientific research institutes, colleges and universities, chemical experiments, security, public safety, biology and medical fields to study the judgment and confirmation of material components, and can also be used in criminal investigation and jewelry and jade industries to conduct drug detection Detection and identification of gemstones for jewelry. [0003] The Raman probe is the basic detection component of the Raman spectrometer. At present, there are many forms,...
