Environmental Protection
★ Motor / Vehicle Exhaust Gas Tester ★
◆ Differential Optical Absorption Spectroscopy (DOAS)
DOAS is used to measure concentrations of trace gases. The principle is that gas molecules have different absorption characteristics in different optical wavelength. With simple equipment and excellent monitoring capabilities, DOAS technology has been used in the environmental industries in many countries. According to the global development report of the environmental monitoring market, the market scale is estimated to $ 19.6 billion in 2021. In addition, because of Asian countries’ stricter environmental policies and rapid development of the green energy technology in recent years, OtO Photonics’ spectrometers have also been actively deployed into these potential markets.

★ Continuous Emission Monitoring Systems (CEMS) ★
In order to measure the composition and concentration of trace gas precisely, according to the absorption characteristics of DOAS in the spectrum and the corresponding algorithms, many online monitoring systems for air quality was developed and designed on the market. OtO Photonics has launched HB2034 / HB2094, SE2030 / SE2090 and OW1030 spectrometers. These modules can be customized resolution up to 0.1 ~ 0.5nm with high SNR and fast sensor.

▲ OtO Photonics Spectrometer - HB Series / SE Series / OW Series
OtO Photonics has devoted to customized design services, we have compelling quality and competitive prices of our products, and also technical support for software and firmware, allowing spectrometers can be widely used in the environment monitoring industry. OtO Photonics is the only leading manufacturer in Taiwan which is capable of developing modular spectrometers.
The mechanism of the SE / HB / OW is based on the Czerny Turner design, with the patented rotatable grating mount which can help accurately calibrate spectrometers. In addition, the control board with temperature detection chip can avoid measurement errors caused by temperature changes. Our spectrometers can maintain stable wavelength accuracy and optical resolution from -10 ° C to 50 ° C environmental conditions.
Moreover, OtO Photonics provides flexible hardware or software trigger mode and light source settings, which effectively improves the online measurement applications, giving system integration manufacturers the most convenient choice. Our spectrometers can also be chosen for designated output, such as WIFI or Bluetooth interface. By applying to the Industrial Internet of Things (IIoT), spectrometer becomes a smart tool for intelligent control and real-time monitoring.
