China Gas Sensing Lasers Supplier

Gas Sensing Lasers constitute a class of precision-wavelength lasers specifically designed for gas absorption spectroscopy analysis. By precisely matching the absorption lines of specific gas molecules, they enable highly selective and highly sensitive detection of gas concentrations. Box Optronics primarily offers DFB (Distributed Feedback) lasers in 14-pin butterfly packages, featuring stable single-mode/polarization-maintaining output, precise wavelength control, and excellent temperature control performance. These devices are widely utilized in high-precision gas analysis systems, such as TDLAS (Tunable Diode Laser Absorption Spectroscopy).

The product range covers wavelengths corresponding to numerous critical gas absorption lines—including 760 nm, 1392 nm, 1512 nm, 1532 nm, 1567 nm, 1625 nm, 1651 nm, 1653.7 nm, and 1683 nm—enabling the detection of various gases relevant to industrial, environmental, and energy sectors, such as oxygen (O₂), water vapor (H₂O), ammonia (NH₃), acetylene (C₂H₂), carbon dioxide (CO₂), and methane (CH₄). Typically housed in a 14-pin butterfly package, these products support TEC cooling, incorporate thermistors, and offer optional built-in isolators to ensure long-term, stable operation.

Box Optronics gas detection lasers are suitable for applications ranging from scientific research and validation to instrument development and industrial-scale deployment.
