Product Overview

The Optilab DFB-B series are Distributed Feedback (DFB) laser sources in bench top housing. They are designed for general laboratory applications. DFB-B is a reliable and cost effective DFB laser source for providing up to 8 DFB wavelengths. With Optilab’s comprehensive inventory of high quality lasers, the DFB source can be ordered from a large variety of wavelengths. DFB lasers operating temperature and drive current are precisely monitored by micro-controller to ensure constant output power and emission wavelength stability.

Using its intuitive front panel or an optional RS-232 interface, the user can control the DFB output power level by adjusting the laser drive current and emission wavelength. Optilab DFB Laser Source products are constructed with Telcordia-qualified laser to ensure 15+ years of operating life, backed by a industry leading three year warranty.
