3240nm Single frequency DFB Laser     


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.

Note:

Caution: Before operating the TEC, the housing must be connected to a suitable heatsink

Note: The cap is no heatsink and not suited to be used as contact with a heatsink. Only use the bottom of the base plate for this purpose.

Note: The cap must not be used as base for any fixtures as e.g. collimation
