The distance between the center wavelength of the excitation and emission filter peak should be at least 50 nm. Very often excitation and emission peaks are very close together and it is very important to avoid any overlapping of the filter wavelengths. To achieve this, you can easily select excitation filters with a shorter wavelength than the excitation peak and an emission filter with a longer wavelength than the emission peak. This will still produce enough light for an acceptable 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 and customized filters are available on request.
