Problems solved by technology

[0003] Since the spectroscopic device 1 is not provided with an optical element for uniformizing the light, the monochromatic light generated by the spectroscope 12 is not uniform on the irradiation plane 10, as figure 2 As shown, the light intensity at the center of the irradiation plane 10 is the strongest, and the light intensity becomes weaker towards the periphery of the plane. The unevenness of the light is too serious, resulting in the inability of the light to irradiate the entire sample evenly, which affects the subsequent Spectral measurement results and accuracy of sample analysis

Abstract

Provided is a Spectroscopic device being able to improve evenness, including: a light source unit, a beam splitter, a set of first light, a light, and a set of the second lens. The spectrometer is used to make the light source the light unit by monochromatic light is produced. The light piece includes a hollow columnar ontology, a lie in the inside of the body surface reflective film, a set of towards the first lens into the smooth surface, a reverse of the smooth surface of the smooth surface, and a surrounding the light source unit of an axis and reflects the light multiple reflector, the reflective surface is defined for a light through a channel. With the light a light homogenization effect, can make in a samples on the irradiation plane under uniform illumination, improve spectrum measurement and the accuracy of analysis.

Description

technical field [0001] The invention relates to a spectroscopic device, in particular to a spectroscopic device which is applied to spectrum measuring equipment and can improve light uniformity. Background technique [0002] refer to figure 1 , is a known spectroscopic device 1 , mainly comprising: a light source 11 and a spectroscope 12 . The light emitted by the light source 1 can be introduced into the beam splitter 12 by optical elements such as reflectors and collector mirrors not shown in the figure. Monochromatic light can be irradiated to an illumination plane 10 directly or after passing through other optical elements. The illumination plane 10 can be placed on a sample to be measured, and the sample is connected to a measuring device, and different spectral measurements can be performed according to different measurement methods, such as absorption spectrum, reflection spectrum, transmission spectrum, etc., thereby It is used to analyze the chemical composition,...
