On March 26th, Yuanfang Optoelectronics stated on the “Easy Interaction” platform of the Shenzhen Stock Exchange that the company has the capability to develop terahertz spectrometers. The terahertz spectrometer was previously considered to be an effective instrument for the detection of "oil in the trenches", that is, the remote radio and television has the ability to develop and test the trench oil detector, which has received great attention from the market.

Remote photoelectric products include LED test instruments, photometers, spectroradiometers, etc., which are mainly used for LED and lighting tests. The company stated that high-precision rapid spectroradiometers and photometers are similar to food safety detectors in principle. Because the company has a core technology reserve in spectrometers, it can be developed for food safety, water quality, and other technical upgrades. Products such as color detection products; and whether they eventually invest in R&D to enter these areas will also depend on operating conditions.

Analysts said that the detection of waste oil is one of the major issues that need to be solved in the field of food safety in China. Terahertz technology can effectively identify waste oil. According to reports, the application principle of terahertz spectrometer in the field of food safety detection is to form a spectral pattern of waste oil by changing the light source of the terahertz, and then to compare the spectrum of the detection object to make a discrimination.

Terahertz spectrometer has been strongly sought after by the market. In October of last year, there were rumors that Daheng Technology was involved in the development of terahertz spectrometers. The company later acknowledged that it was leading the development of terahertz time-domain spectrometers, leading to a two-day daily limit for stocks. In December, Daheng Technology announced the terahertz spectrometer again. The project was declared as a national major scientific instrument and equipment development project, approved by the Ministry of Science and Technology, and its share price has reached a daily limit of three days.
