Product Overview 

 

The Optilab DFB-4-B series products are Distributed Feedback (DFB) laser sources in 
bench top housing. They are designed for general laboratory applications. DFB-4-B is 
a  reliable  and  cost  effective  DFB  laser  source  for  providing  up  to  4  different  DFB 
wavelengths.  With  Optilabs  comprehensive  inventory  of  high  quality  DFB  lasers,  the 
DFB  light  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.  With  its simple and 
intuitive front panel interface, the user can control the DFB light source output power 
level by adjusting the laser drive current.

Features 

  Orderable in a variety of wavelengths and power levels 

  Up to four DFB sources per benchtop device 

  Front panel power and wavelength adjustment control via touchscreen display 

  LabVIEW software interface 

  Economical and user friendly
