This product is a distributed feedback (DFB) semiconductor laser specifically designed for methane (CH4) gas detection. Its center wavelength is precisely locked at 1653.7 nm, perfectly corresponding to the characteristic absorption peak of methane molecules, making it an ideal light source for building highly sensitive gas sensing systems.
