  • Methane Laser Sensor: Efficient and Accurate Gas Detection Solution
    Methane Laser Sensor: Efficient and Accurate Gas Detection Solution Nov 22, 2024
    Introduction: Gas detection has become increasingly important in modern industry and environmental monitoring. One of the key tasks is to detect methane gas concentration, as methane is a common greenhouse gas that has significant impacts on climate change and environmental safety. In order to provide efficient and accurate gas concentration detection solutions, methane laser sensors have emerged. This article will introduce the principle, advantages, and application areas of methane laser sensors. Principle: The methane laser sensor is based on Laser Absorption Spectroscopy (TDLAS) technology. It uses a laser beam with a specific wavelength of 1653.7nm to measure the absorption spectrum of methane molecules in the gas being tested. By measuring changes in absorption intensity, the concentration of methane gas can be derived. This technology has the characteristics of high sensitivity, fast response, and high resolution.                   Advantages: Compared to traditional gas sensors, methane laser sensors have the following advantages: a) High sensitivity: Methane laser sensors have high sensitivity to methane gas and can detect extremely low concentrations of methane, typically in the ppm (parts per million) or ppb (parts per billion) range. b) Accuracy: Laser absorption spectroscopy technology can provide highly accurate measurement results, reducing false alarms and errors. c) Real time monitoring: The methane laser sensor has real-time monitoring function, which can quickly respond to emergency situations such as methane leakage and improve safety. d) Long lifespan: The methane laser sensor uses a reliable laser light source, which has a long service life and stability. Application areas: Methane laser sensors have a wide range of applications in various fields, including but not limited to: a) Industrial safety: Methane laser sensors can be used for monitoring methane leaks in fields such as petroleum, natural gas, and chemical engineering, providing rapid response and ensuring the safety of the working environment. b) Environmental monitoring: Methane is a greenhouse gas that has a significant impact on climate change. Methane laser sensors can be used for environmental applications such as atmospheric monitoring and greenhouse gas emission monitoring, helping to assess and reduce methane emissions. c) Mine safety: Methane is a common combustible gas that can easily cause explosions during mining operations. Methane laser sensors can be used for methane gas detection and alarm, ensuring the safety of miners. d) Gas energy detection: Methane is the main component of natural gas, and methane laser sensors can be used for natural gas exploration and downhole operations, providing key gas concentration information. Conclusion: Methane laser sensors, as an efficient and accurate gas detection solution, are widely used in industrial and environmental fields. Its high sensitivity, accuracy, and real-time monitoring capabilities make it an important tool for improving safety and environmental monitoring levels. With the continuous advancement of technology, methane laser sensors will continue to develop and play a role in more fields, promoting sustainable development and environmental protection.

    New industrial park helps product transformation, 400G/800G OEM services debut in the industry Sep 20, 2023
    During the 2023 CIOE, Xiamen SAN-U Optronics Co., Ltd. (referred to as SAN-U Optronics), a provider of high-speed semiconductor lasers/detectors and optical transceiver components, showcased a series of 25G/50G/100G optical devices and COB optical engine products, which are widely used in fields such as cloud computing, optical communication, fiber to the home, sensing and detection, and LiDAR. Dr. Li Ling, Chairman of Sanyou Optoelectronics, was interviewed by Xunshi Optical Communication Network on site. She stated that the company mainly exhibited three major application products, data communication, optical sensing, and airtight packaging, at this year's CIOE China Optical Expo, showcasing the leading intelligent manufacturing platform for optoelectronic devices in China. The products have received high-end attention from industry customers. In terms of data communication, SAN-U Optronics has successfully expanded its 400G/800G OEM services based on its existing high-speed optical engine technology product foundation. With the explosion of AI computing power connectivity in 2023, the demand for 800G optical communication has exceeded everyone's expectations. The entire industry is preparing sufficient materials for the delivery of 800G products, among which 400G/800G high-speed chips are still the most scarce key materials in the supply chain, bringing a new round of development opportunities for domestic optoelectronic chips. After more than 20 years of development, Sanyou Optoelectronics' optoelectronic chip packaging platform has been widely certified by the industry and customers. It can provide industry-leading chip packaging services and help accelerate the industrialization of domestic chips. In terms of optical sensing, SAN-U Optronics mainly researches and manufactures laser and MEMS sensor products. The company team has conducted in-depth research and development in this new field, and has achieved market breakthroughs in a series of products such as LiDAR, methane gas detection lasers/detectors, MEMS micro pump bio chip packaging and bio printing chip products, and fast detection chip products, receiving good customer feedback. In the context of weak traditional single market, the sensing market has provided strong performance support for the company. In addition, in terms of the application of airtight packaging technology, SAN-U Optronics has successfully introduced airtight packaging technology into the field of third-generation semiconductor materials, mainly in the new energy industry dominated by silicon carbide (SiC). With the prosperity of the new energy vehicle industry, silicon carbide has become the hottest semiconductor material, and related domestic silicon carbide materials and devices are rapidly rising.
