Switch Box Kit for the Model SFA Fluorescence Adapter
The Switch Box Kit is an accessory for the NIGHTSEA Model SFA Stereo Microscope Fluorescence Adapter. It enables you to mount two different wavelength excitation light heads on your microscope and switch between them easily. You will still need to manually change the barrier filter, but it eliminates the need to swap out light heads on the gooseneck.

How does this work?
The switch box kit consists of:
- BNC Switch box
- Three BNC cables
- Two Light Head Hangers
One BNC cable connects the SFA gooseneck lamp base to the input connector on the rear of the Switch Box. The other two cables connect the Switch Box outputs to the two light heads. Use the selector switch on the front of the Switch Box to select between the two light heads. The Light Head Hangers mount your light heads on the SFA adapter ring on the microscope.
