NIGHTSEA® Switch Box Kit for the Model SFA Stereo Microscope Fluorescence Adapter

EMS Catalog #SFA-SWK

The Switch Box Kit is an accessory for the NIGHTSEA Model SFA Stereo Microscope Fluorescence Adapter. The Switch Box Kit 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.

The Switch Box Kit is available only for SFA systems that use the BNC light head connector, and not the older V1 connector.

The switch box kit consists of:

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.

  • SFA Switch Box front, showing selector switch
  • SFA Switch Box rear, showing input and output connectors
  • SFA Switch Box Kit, position A, RB selected
  • SFA Switch Box Kit, position B, GR selected
 

( Note - Light heads not included with kit. Any of the BNC light heads can be used with the kit.)

The Light Head Hangers mount to the end of any of the thumbscrews on the SFA adapter ring.

Note that the Switch Box Kit is currently available only for SFA systems that use the BNC light head connector, and not the older V1 connector.

What is the benefit?

This accessory simplifies the process of switching between excitation wavelengths. You can have two different excitation sources mounted simultaneously and select between them with the flip of the selector switch. You will still need to manually change the barrier filter, but the overall switching process is speeded up and simplified.
