YSL Photonics’ VLF wavelength selection system is based on the linear variable filter technology, offering tunable wavelength

from 400nm to 840nm. Moreover, the linewidth could be varied from 10-300nm, making it an ideal solution for fluorescence 

microscopy, nanophotonics and other application areas. The standard output of the VLF is a free-space collimated beam, as 

an option, the output can also be single mode fiber with FC connector.
