Product Description:
The VCSEL products for gas sensors produced by Vertilas in Germany have multiple wavelengths, meeting the detection requirements for most commonly used harmful gases. 1854nm VCSEL can be used for water measurement. VCSEL lasers have high current dependence for gas detection and typically have a tunable wavelength range of 4nm, making them particularly suitable for TDLAS measurement methods. Meanwhile, VCSEL has the advantages of simple structure, stable batch production, and high cost-effectiveness.
Vertilas offers standard product wavelengths including 1273nm, 1392nm, 1512nm, 1566nm, 1570nm, 1580nm, 1590nm, 1654nm, 1742nm, 1854nm, 2004nm, and 2012nm. It can be used for the detection of gases such as CO (carbon monoxide), NO (nitric oxide), H2O (water vapor), NH3 (ammonia), HCl (hydrogen chloride), H2S (hydrogen sulfide), CH4 (methane), N2O (nitric oxide), CO2 (carbon dioxide), etc. We can also provide lasers with the wavelength specified by the customer.
