Description

Technical Field

[0001] This utility model relates to the field of infrared spectrometer technology, specifically to an infrared spectrometer reflection component. Background Technology

[0002] An infrared spectrometer is an instrument that analyzes the molecular structure and chemical composition of substances by utilizing their absorption characteristics of infrared radiation at different wavelengths. It typically consists of a light source, a monochromator, a detector, and a computer processing system. Depending on the spectroscopic device, it is classified as dispersive or interferometric. Infrared spectrometers have wide applications in various fields, including industry, agriculture, medicine, science, and the military. In the medical field, infrared spectrometers help medical experts understand the molecular structure and chemical composition of different substances by analyzing the absorption characteristics of infrared light in samples.

[0003] A search revealed Chinese utility model patent CN218470531U, which discloses a reflective component for an infrared spectrometer. The component includes a monochromatic box with a light-shielding mechanism on its left side. A connecting pipe located below the light-shielding mechanism is connected to the right side of the monochromatic box, and a detection box is connected to the right side of the connecting pipe. A first reflecting mirror, located to the right of the connecting pipe, is fixedly connected to the front and rear side walls of the inner cavity of the detection box. A reflection detector located below the first reflecting mirror is fixedly connected inside the detection box. This reflective component for an infrared spectrometer offers advantages such as high detection accuracy. It solves the problem that most existing infrared spectrometers detect refracted and transmitted light by refracting natural light through a sample. When natural light passes through the sample, it is refracted by crystals within the sample, resulting in scattering and inaccurate transmitted light readings.

[0004] The existing device has the following problems when in use: the reflector in the infrared spectrum can only reflect the same type of substance. When different substances need to be detected, different reflectors need to be replaced. However, replacing the reflector is very complicated and troublesome, which increases the complexity of use.

[0012] Preferably, sliders are provided on both sides of the first, second, and third reflectors, and the sliders are slidably connected to slide rails.

[0013] By adopting the above technical solution, the first, second, and third reflectors maintain a straight line motion during use, avoiding deviation that could lead to unsatisfactory reflective effects.

[0019] By adopting the above technical solution, the door is opened and the object to be detected is placed on the placement plate. When the second reflector is not in use, it retracts into the control compartment B.
