Our team designs and manufactures the most diverse fluorescent filters in the industry for biomedical fluorescence detection and high resolution requirements analysis systems such as PCR analyzers, POCTs, fluorescence microscopy, flow cytometry, etc. Welcome to the optimization of the fluorophores, using the superb coating process, the crosstalk coefficient of the fluorescence filter manufactured by Wendi in the multi-channel fluorescence test has reached a very low ideal level.
Product advantages
■ No wavelength drift – providing precise and stable center wavelengths;
■ High transmission rate – ensuring maximum signal collection efficiency;
■ High cut-off steepness – cut off the excitation light in the fluorescent emission band for better contrast;
■ High cut-off depth – ensures optical system background noise is minimized and signal to noise ratio is maximized;
