The distance between the centre wavelength of the excitation and emission filters should be at least 50 nm. Very often excitation and emission peaks are very close together, but it is important to avoid any overlapping of the filter wavelength; to achieve this, you can easily select excitation filters for a shorter wavelength than the excitation peak, and emission filters for a longer wavelength than the emission peak, and still catch enough light for a nice signal-to-noise ratio.
Please contact our product specialists or sales representatives to help you select the best filters for your application. We have optimized filter sets for many different applications in our program. Alternatively, customized filters are available on request.
