For more than 20 years nanoplus has been the technology leader for lasers in gas sensing. We produce lasers at large scale at our own fabrication sites in Gerbrunn and Meiningen. nanoplus cooperates with the leading system integrators in the TDLAS based analyzer industry. More than 30,000 installations worldwide prove the reliability of nanoplus lasers.
Quick description of nanoplus DFB laser technology
nanoplus uses a unique and patented technology for DFB laser manufacturing. We apply a lateral metal grating along the ridge waveguide, which is independent of the material system. Read more about our patented distributed feedback technology.
