Multifunctional microscopic confocal spectrometer

Abstract

The invention discloses a multifunctional microscopic confocal spectrometer. The multifunctional microscopic confocal spectrometer comprises a laser module, an optical path coupling and output main module, an illumination observation module, a microscopic module and a signal detection module, wherein the optical path coupling and output main module and the illumination observation module share one base, the laser module is fixed on the rear side surface of the base, the microscopic module is fixed on the front side surface of the base, and the signal detection module is fixed on the right side surface of the base. According to the invention, microscopic observation of samples of corresponding laser spots is realized, the microscopic confocal test of a sample Raman signal and a photoluminescence signal can be conveniently carried out, and the multifunctional microscopic confocal spectrometer is simple in structure, good in stability, convenient to adjust and convenient to expand.

Description

technical field [0001] The invention relates to the technical field of microscopic spectrometers, in particular to a multifunctional microscopic confocal spectrometer which has the advantage of low cost and is easy to expand. Background technique [0002] Existing microconfocal spectrometers integrate lasers, microscopes, confocal pinholes, gratings, and detectors, such as figure 1 shown. In these commercial micro-confocal spectrometers, the grating and detector have been integrated with the micro-confocal optical path and cannot be separated, making it inconvenient to expand the function. Moreover, the integration of the whole system makes the use cost of the spectrometer very high, for example, the price of common commercial confocal micro spectrometers on the market is very expensive. [0003] In addition, for the micro-confocal spectrometer, how to make the laser spot consistent with the image point of the confocal hole on the sample is the key to be able to measure th...
