Color Coding SFA Light and Filter Sets

We offer five different fluorescence excitation light sources for the Model SFA Stereo Microscope Fluorescence Adapter. Knowing which emission barrier filter or shield should be used with each light source is not hard if you have a good working knowledge of fluorescence, and the pieces are all color coded with a color strip to avoid confusion.

In choosing how to color code, the decision was made to coordinate with the light source color, rather than the expected fluorescence emission color. If the only use was with fluorescent proteins, the expected emission could be used, however the world has a vibrant palette of fluorescence response. One excitation may elicit a broad spectrum of color responses. The color coding of all three pieces in a light/filter set (the light head, barrier filter, and filter shield) corresponds to the color of the excitation source.
