Pioneering Fluorescence

We specialise in the design and manufacture of high performance, optical interference filters for fluorescence microscopy. We offer an extensive selection of dye-specific Fluorescence Filter sets for single and multi-label microscopy applications, including GFP, Pinkel, Ratio-Imaging, FRET, and other techniques.

We have pioneered developments in filter technology for fluorescence microscopy. Over the years, innovation in product design focused on improving throughput and polarisation, while minimising auto-fluorescence and cross-talk. The resulting optimised filter sets for epi-luminescent microscopes have enhanced the ability of life scientists to isolate small Stokes-shifted energy of low intensity and image complex cellular structures and processes.

From the beginning, our filter technology inventions has stimulated the science of optical microscopy and fluorescence detection. We remain committed to pushing the limits of the science through collaboration with researchers and manufacturers worldwide.

General Features

All our fluorescence filter sets are optimised to maximise emission collection and minimise optical degradation by using specialised optical polishing and anti-reflective coatings. Exciters are high performance bandpass filters with reflective metal layers tolerant to intense excitation sources. Dichroics are hard surface coated. Emitters are anti-reflection coated to minimise back reflection and enhance transmission typically to 90%.
