The LD-PD's Distributed Feedback Lasers (DFB) are specifically designed for high-precision gas detection using tunable diode laser absorption spectroscopy (TDLAS). Our devices operate reliably in more than 40,000 installations worldwide. For more than 10 years LD-PDshas set the standard for DFB laser technology and we manufacturer routinely providing DFB lasers at any wavelength.
