535nm带通滤光片

Use CWL 535 nm with 20–50 nm FWHM for green LED illumination, source cleanup, or practical green-band output.

Green LEDs have broader emission than laser sources, so medium or broad filters are usually more practical than ultra-narrow filters. Use 20 nm FWHM when the setup needs stronger wavelength selection around 535 nm. Use 40–50 nm FWHM when the system needs more usable green output.

Use CWL 535 nm with 20–50 nm FWHM to select a practical green band from xenon, halogen, white-light, or other broadband visible sources.

For broadband visible illumination, the filter extracts a 535 nm-centered green band from a wider spectrum. Use 20 nm FWHM when the setup needs a more defined green band. Use 40–50 nm FWHM when higher transmitted signal is more important for illumination, imaging, or detection.

Use CWL near 535 nm with 20–50 nm FWHM when collecting green fluorescence emission from FITC/fluorescein/Alexa Fluor 488/GFP-type or YFP/Venus/mCitrine-type emission signals.

For fluorescence microscopes, flow cytometers, or fluorescence detection systems, the 535 nm filter is usually placed before the detector, camera, PMT, or spectrometer input. The excitation filter should be selected around the excitation source wavelength, while the 535 nm filter collects the green emission band.
