    3. Application:

    Fluorescence detection bandpass filter is mainly used for fluorescence microscope and fluorescence qualitative instrument.

    Fluorescent filters are widely used in biochemical analysis neighborhoods. Fluorescent filters generally include two types: excitation filter and emission filter.

    Excitation filter (Exciting Filter, Exciter Filter, Excitation Filter): in a fluorescence microscope, only a filter that can pass the wavelength of the fluorescence can be passed. There is also the direct use of laser as a stimulated luminescence.

    Emission filters (Emitting Filter, Emission Filter, Barrier Filter, Emitter): select and transmit the fluorescence emitted by the sample, and the other light rays cutoff. The wavelength of the emitting light is longer than that of the stimulated luminescence. The bandpass filter or the long pass filter can be selected as the transmitting filter.

    The fluorescence filter of 470nm belongs to the excitation fluorescence filter.
