These optical filters for fluorescence microscopy are hard coated, with a patented construction that gives superior performance. Steeper edges, precise wavelength accuracy and optimised blocking give better contrast and faster measurements, even at UV wavelengths. These filters do not burn out and can be handled and cleaned safely. Their simple structure and hard coating makes them virtually impervious to humidity and temperature induced degradation. All standard filters have a 10-year warranty. The 30-day free trial period allows you to try before you buy, and ensure that the filter set meets your needs.
