SpectraSplit is a combination of light filter sets which enables simultaneous and clearer detection of
up to eight labeled structures – without losing the sensitivity for its fluorochrome.


Fluorescence microscopy

Fluorescence microscopy enables visualization of several proteins within the same tissue sample (multicolor microscopy). Key parts in multicolor microscopy are the filter sets in the microscope. The filters sets assure that light from each fluorochrome are correctly filtered to generate distinct and specific signals. There are three basic filters in fluorescence microscopy: excitation filters, emission filters and dichromatic beam splitters. These three filters form a filter set that usually are mounted into a filter cube. Proper selection of each filter component is critical to successful fluorescence microscopy.

For more background understanding of fluorescence microscopy, we recommend JoVE’s science education videos.


A simple and powerful microscope upgrade

SpectraSplit is a combination of carefully selected light filters to generate more and clearer channels in standard fluorescence microscopy. SpectraSplit permits a much more economic use of the available light spectrum by splitting up each of the common channels (green, red, and far-red) into two separate channels.

The channel splits are obtained by the use of condensed filter sets that each occupies a much smaller portion of the light spectrum, without losing the sensitivity for its fluorochrome. In fact, the SpectraSplit filter sets have improved signal-to-noise ratios due to its optimized placement of excitation and emission filters that further favor the fluorochrome signal over the background noise.
