Detection equipment and method for laser confocal Raman spectrometer

Abstract

The invention discloses detection equipment and method for a laser confocal Raman spectrometer. The detection equipment comprises a mounting plate, a first movable frame and a second movable frame. The top of the mounting plate is fixedly connected with a protection box, and the bottom of the inner cavity of the protection box is fixedly connected with an inner box. A detector element body is fixed by arranging a supporting rod, a supporting plate and a connecting rod, and meanwhile, the connecting rod is fixed through a bolt and is convenient to disassemble and overhaul. By arranging a temperature sensor, the working temperature of the detector element body can be monitored in real time, and temperature information can be transmitted to a PLC. A heat dissipation fan is arranged and can be started by the PLC to dissipate heat of the detector element body when the temperature exceeds a set value of the temperature sensor, so that the problem that a detector element in a Raman spectrometer can generate high temperature in the using process, and if the high temperature cannot be effectively reduced in time, the detector element is prone to being damaged is solved.

Description

technical field [0001] The invention relates to the technical field of Raman spectrometers, in particular to a detection device and method for laser confocal Raman spectrometers. Background technique [0002] Raman spectroscopy is a kind of scattering spectrum. Raman spectroscopy is based on the Raman scattering effect discovered by Indian scientist C.V. Raman. It analyzes the scattering spectrum different from the incident light frequency to obtain molecular vibration and rotation information, and An analytical method applied to the study of molecular structure, the inelastic scattering produced by the interaction of molecular vibrations, optical phonons in solids, etc., and laser light is called Raman scattering. [0003] Raman spectroscopy imaging technology is the perfect combination of confocal microscopy technology, laser Raman spectroscopy technology and new signal detection devices, and expands the simple single-point analysis method to comprehensive analysis of samp...
