This product is a vertical-cavity surface-emitting laser (VCSEL) specifically designed for oxygen (O₂) gas detection. Its center wavelength is precisely locked at 760nm, perfectly corresponding to the characteristic absorption peak of oxygen molecules. It uses a TO60 package and integrates a TEC thermoelectric cooler, making it an ideal light source for building high-sensitivity, low-cost gas sensing systems.

Precise wavelength locking: With a center wavelength of 760nm, it is optimized for O₂ detection, ensuring high selectivity and effectively avoiding cross-interference from background gases.
