Fluorescence filter - أطلس مختبرات العرب

Epi-fluorescence interference and absorption filter combinations are housed in a filter cube (or optical block) and include an excitation filter, dichromatic beamsplitter (often referred to as a mirror), and a barrier (or emission) filter, as illustrated in Figure 1(a). Use this guide in selecting the appropriate filter set to match the spectral excitation and emission characteristics of chromophores used in widefield fluorescence microscopy investigations. The spectral profiles of a typical high-performance bandpass emission blue excitation filter combination are presented as an example in Figure 1(b). Nikon fluorescence filter combinations are provided in narrow, medium, and wide passband excitation versions with corresponding emission filters available with either bandpass or longpass spectral characteristics
