Stereo Microscope Fluorescence Adapter

New faculty in 2017? Apply for the KEY Award to receive a Model SFA fluorescence adapter system plus $750 in lab supplies.

Watch our brief (2:39) intro showing you how easy it is to add fluoresence in about 30 seconds.

The 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.

A complete system with one excitation/emission combination includes just 6 items:

  • Needed once:
    1. Flexible gooseneck lamp base with control circuit
    2. Power supply that operates from 120/240VAC, 50/60Hz
    3. Simple adapter that mounts on virtually any existing stereo microscope
  • Included in light + filter set:
    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

You only need the first group one time. Wavelength combinations are supplied in a light + filter set consisting  of a light head, barrier filter, and viewing shield in a custom foam-lined box. 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.

Wavelength sets

NOTE – Wavelength sets are named and color coded for the color of the excitation light, not the color of the emitted fluorescence. Read more …
