Leica Wins FDA Clearance for Novel Microscopy Filter

Leica Microsystems won FDA clearance for its FL560 fluorescence microscope filter for use with the dye fluorescein to view cerebrovascular blood flow.

The device works with the M530 OH6 neurosurgical microscope. After injection of fluorescein, the surgical team can see blood fluorescing in greenish/yellow, providing   contrast between the blood flow and surrounding anatomy so both can be seen.

Using two illumination methods, the device can treat fluorescence differently than white light.
