Abstract

The invention relates to an embedded combined excitation light source suitable for a fluorospectro photometer. The embedded combined excitation light source comprises a thermal light source light path module, a cold light source light path module and a cold / thermal light source circuit switching module, wherein the thermal light source light path module comprises a thermal light source, a first lens, an EX optical splitter and a second lens; the cold light source light path module comprises a cold light source assembly and a corresponding third lens; and the cold / hot light source circuit switching module is connected with the hot light source and the cold light source to achieve switching of the cold light source and the hot light source. According to the embedded combined excitation light source, the fluorospectro photometer is simultaneously provided with two light sources with different light-emitting mechanisms, namely the thermal light source and the cold light source, so that the cold light source can be selected when a detected sample which is easily decomposed or thermally fluctuated by irradiation light is encountered; and when a cold light source is adopted and the EX wavelength required by the test cannot be provided, a thermal light source can be selected, so that the required EX wavelength can be obtained from the continuous wavelengths of the light source. Therefore, the test range of the fluorospectro photometer is expanded, and the test cost is saved.

Description

technical field [0001] The invention relates to an embedded combined excitation light source suitable for a fluorescence spectrophotometer, belonging to the technical field of fluorescence analysis and detection. Background technique [0002] Fluorescence occurs because a substance with fluorescent properties emits light with a wavelength longer than that of the excitation light after absorbing the excitation light. refer to figure 1 , when the light beam radiated by the light source passes through the EX beam splitter to form monochromatic light and irradiates the sample cell, the fluorescent substance in the sample absorbs the excitation light and undergoes an energy transition to emit fluorescence. Fluorescence is irradiated on the photomultiplier tube after being concentrated by the large-aperture aspheric mirror and the spectroscopic dispersion by the grating. The photomultiplier tube converts the optical signal into an electrical signal, and the electrical signal is a...
