This video (2:50) introduces the SFA system in the way that we do it when we are exhibiting at a conference.

A brief (2:39) intro showing you how easy it is to add fluorescence to virtually any existing stereo microscope in about 30 seconds. Note that this video includes our original, older-style connector for the light head. The videos above and below show the current connector.

And a 1 minute video showing the system being added to a microscope.

The Model SFA Stereo Microscope Fluorescence Adapter is a complete solution for adding fluorescence to existing stereo microscopes. It includes everything you need for adapting (not converting) just about any stereo microscope. You can purchase any of the 6 modular wavelength combinations that you need now and add more at any time. And best of all – it’s just $1,095 to get started with the complete setup for one color ($1,245 for UV).

A complete system with one excitation/emission combination includes these 7 items:

  1. Flexible gooseneck lamp base with control circuit
  2. Power supply that operates from 120/240VAC, 50/60Hz and international plug set
  3. Simple adapter that mounts on virtually any existing stereo microscope
  4. LED light head
  5. Barrier filter that attaches to the adapter with a simple magnetic click
  6. Viewing shield made of matching filter material
  7. Soft-sided case with custom cut foam for protection in transport and storage

If you want a second wavelength combination, either at the time of the original order or some time in the future, you do not need to order another ‘complete system’. You just need the add-on modular excitation/emission set.

Add-on modular wavelength sets include:

  1. LED light head
  2. Barrier filter that attaches to the adapter with a simple magnetic click
  3. Viewing shield made of matching filter material
  4. Case with custom cut foam for protection in transport and storage

The part numbers for these add-on sets include the letters ‘LFS‘ (for Light and Filter Set).

The light head and filters can be removed and replaced in seconds, and color coding ensures that you are using the right combination. All components are also available a la carte.

Ordering/pricing examples


Scenario 1 – You do not own a NIGHTSEA system yet and want to observe GFP

You just need the Royal Blue excitation/emission set. The most common choice is part number SFA-RB, with the longpass filter. If you want the bandpass option the part number is SFA-RB-GO. Both would be priced at $1,095. If you wanted the dimming control (DIM option), the part numbers would be SFA-RB-DIM and SFA-RB-GO-DIM, respectively, price $1,345.

Scenario 2 – You do not own a NIGHTSEA system yet and want to observe both GFP and RFP

You need the Royal Blue and Green excitation/emission sets, but you only need one ‘complete system’. You would order SFA-RB ($1,095) and SFA-LFS-GR ($555).

Scenario 3 – You already own a NIGHTSEA system, for example SFA-RB, and want to add another wavelength set to observe RFP

You just need the add-on modular Green excitation/emission set, SFA-LFS-GR, price $555.
