Problems solved by technology

At present, the light import and export of ATR products on the market mainly use infrared optical fiber, which is expensive
There are also a small number of light guides and guides that use a hollow light guide. Due to the large loss of light, the signal is weak
The previously designed ATR probe uses a DLATGS detector embedded in the probe for detection. In actual use, it is found that when the probe is inserted into the tank of the solution to be tested, the voltage of the tank is enough to cause damage to the DLATGS detector due to the static electricity in the tank, making the ATR probes cannot be used

Abstract

The invention discloses a high luminous flux infrared ATR probe which comprises a light in tube, a first reflecting mirror, a second reflecting mirror, a first inner film coating light tube, a second inner film coating light tube, a crystal and a light out tube. According to the high luminous flux infrared ATR probe, large-caliber hollow light tubes with the inner plating of an infrared high reflectivity film are employed as a light import component and a light export component, and a light signal exported by ATR is sent to a MCT detection room for the detection of light. The ATR probe only comprises a light path which is isolated from a detector, the permeability of light is increased, the detection of a signal is easier, and the damage of detector due to the electrification of a tank body is prevented. At the same time, since an MCT detector is employed, the detection effect is better. So, compared with an existing commercialized ATR probe, the high luminous flux infrared ATR probe has the advantages of low cost, large luminous flux, high signal-to-noise ratio, simple structure and convenient use and has a broad application prospect in the fields of biology, medicine, geology, material science and the like.

Description

technical field [0001] The invention belongs to the field of physical photonics, especially the technical field of spectral analysis instruments, and relates to a high luminous flux infrared ATR probe, in particular to an ATR probe for Fourier transform infrared spectrometer. Background technique [0002] Attenuated Total Reflectance (ATR) spectroscopy is a kind of infrared spectroscopy testing technology, which is widely used in infrared spectroscopy testing techniques. The use of ATR spectrum technology makes the Fourier transform infrared spectrometer do not need any treatment on the sample during the test process, which saves the work of sampling and sample preparation, and will not cause any damage to the sample. [0003] With the development and wide application of Fourier transform infrared spectrometer, this technique has become an important means of frequently used infrared sample testing. In actual application, ATR has shown its unique advantages and broad appli...
