Problems solved by technology
[0007] The purpose of the present invention is to overcome the problems existing in the existing spectrometer: 1) the high energy utilization rate and high resolution cannot be guaranteed at the same time; 2) the interface is single, which is inconvenient to use in special occasions; 3) the leakage switch cannot be installed to protect the circuit. An industrial field spectrometer has been developed. The spectrometer of the present invention realizes the perfect combination of high energy utilization rate and high resolution, and has low manufacturing cost and good use effect

Embodiment 1
[0028] In conjunction with the accompanying drawings, an industrial field spectrometer of this embodiment includes a light collection and collimation module, an imaging module, a processing module and a control module. The light collection and collimation module is used to collect target reflected light, and the collected The light is collimated, split, and processed light is output. The light collection and collimation module includes a light collection collimation lens 2, a cylindrical mirror 3, a slit 4, a collimation lens 5, a grating 6, an imaging lens 7, a DMD 8, a focusing lens 9 and a single-point photodiode 10, so The above-mentioned light-collecting collimator lens 2 and cylindrical mirror 3 constitute a light-collecting structure, and the reflected light of the detection target 1 enters the light-collecting collimator lens 2 through the fiber port, and is collimated by the light-collecting collimator lens 2 into polychromatic parallel light After entering the cylind...

The invention discloses a spectrometer for an industrial field, and belongs to the technical field of spectrometers. The spectrometer comprises a light collecting and collimating module, an imaging module, a processing module, a control module and an interface extending and converting module, wherein the light collecting and collimating module is used for collecting target reflected light, collimating and splitting the collected light and outputting the processed light; a CCD drive circuit in the imaging module is used for controlling a CCD detector to acquire spectrum obtained after the light is processed by the light collecting and collimating module, the processing module is used for processing and displaying spectrum data acquired by the CCD detector, and comprises a signal conditioning unit, a data acquiring unit and a power supply unit, the control module is used for sending control signals to the processing module and the CCD drive circuit, and the interface extending and converting module is used for extending the interface of the spectrometer. An electricity leakage switch is additionally arranged, so that the spectrometer is safer and more reliable to work, and perfect combination of high energy utilization rate and high resolution is realized.
Description
technical field [0001] The invention relates to a spectrometer, in particular to a spectrometer for industrial field use. Background technique [0002] Light is a kind of electromagnetic radiation wave with certain energy. The energy of different wavelengths of light corresponds to a certain quantization energy level difference of electrons in molecules or atoms. When light acts on the substance to be measured, it will cause reflection, absorption and scattering and other phenomena, resulting in the change of the incident light signal. The change of the incident light signal directly reflects the absorption, reflection or scattering of the electromagnetic radiation of the compound atoms or molecules. Spectral technology is to measure the change and obtain the light absorption, reflection or scattering. Spectra for qualitative or quantitative analysis and identification of compounds. [0003] The spectrum of a substance is closely related to the molecular structure, and it i...
