Abstract

The invention discloses an optical microscope beam splitter device which comprises a beam splitter shell and a beam splitter cover plate. The beam splitter cover plate is used for guaranteeing that space in the beam splitter shell does not leak light. Two sets of beam splitting sheet fixing frames are arranged in the beam splitter shell in parallel, one set is used for white light imaging observation, and the other set is used for spectral measurement. A switching mechanism used for switching the two sets of beam splitting sheet fixing frames is further arranged in the beam splitter shell. An in-situ observation white light imaging focus point and a laser in-situ measurement point of a measured sample are kept consistent by switching a double-beam-splitting-sheet white light imaging observation module and a spectral measurement full-reflection mirror module, the utilization ratio of light intensity of incoming lasers and the efficiency of collecting light signals (raman scattering light or fluorescent light) from the sample are improved, and the testing space resolution and testing sensitivity are improved.

Description

technical field [0001] The invention belongs to the field of optical microscope instrument design and microscopic spectrum measurement, and in particular relates to an optical microscope beam splitter device for fast white light imaging observation and high-sensitivity / high-spatial-resolution in-situ spectrum measurement of a portable spectrometer. Background technique [0002] The optical microscope organically combines microscopic technology, photoelectric conversion technology, and liquid crystal screen technology to display the fine structure of the sample surface. It has been widely used in optical measurements in the fields of physics, chemistry, biology, materials, and physical evidence. Beam splitter is one of the important optical components for image observation in optical microscope. Ordinary optical microscopes usually only install a beam splitter at an angle of 45 degrees to the incident light, which divides the incident light into two beams of transmitted and r...
