4 Channel DFB Laser Source, Benchtop
The Optilab DFB-4-PM-B is a Distributed Feedback (DFB) laser source in a benchtop unit designed for general laboratory applications. The DFB-4-B is a reliable and high-performance DFB laser source for providing up to 4 DFB wavelengths. With Optilab’s comprehensive inventory of high quality lasers, the DFB-4-B source can be ordered from a large variety of wavelengths, and is constructed with Telcordia-qualified laser to ensure 15+ years of operating life. The DFB laser’s operating temperature and drive current are precisely monitored by a micro-controller to ensure constant output power and emission wavelength stability. Using its intuitive front panel or an optional USB interface, the user can control the DFB output power level by adjusting the laser drive current and emission wavelength via TEC. Contact Optilab for more information.
