A Portable and Adjustable Raman Probe

Abstract

The invention discloses a portable adjustable Raman probe which comprises an integrated housing, an optical fiber emitting port, an optical fiber receiving port, a receiving condensing lens, an emitting condensing lens, a band-pass filter, a long-pass filter, a reflecting mirror, a dichroic mirror and a laser emitting / receiving probe, wherein an emitting channel and a receiving channel are formed in the integrated housing; the optical fiber emitting port, the emitting condensing lens, the band-pass filter and the dichroic mirror are arranged in the emitting channel in sequence; the dichroic mirror is obliquely mounted at the tail end of the emitting channel; the optical fiber receiving port, the receiving condensing lens, the long-pass filter and the reflecting mirror are arranged in the receiving channel in sequence; the reflecting mirror is obliquely mounted at the tail end of the receiving channel; the reflecting surface of the reflecting mirror corresponds to the dichroic mirror; the laser emitting / receiving probe is detachably mounted on the integrated housing. According to the Raman probe, the universality of a laser Raman spectrum detection system is greatly improved.

Description

technical field [0001] The invention relates to an optical device, in particular to a laser Raman probe. Background technique [0002] Since the discovery of Raman scattering by Indian scientist C.V.Raman in 1928, laser Raman spectroscopy detection technology has been used as a spectral analysis technology because it can provide fast, simple, repeatable and more importantly non-destructive Qualitative and quantitative analysis is widely used in the inspection of various chemical substances, such as judicial identification, safety inspection, jewelry identification, crystal research and drug identification. Raman spectroscopy and infrared spectroscopy can complement each other, and its main advantages are reflected in the following points: First, laser Raman spectroscopy detection technology does not require sample preparation, and has low requirements for sample shape, size, temperature, and state. It can be measured in physical states such as solid, liquid, gas, and soluti...
