General Introduction:Fluorescence filter is a key component used in biomedical and life science instruments. Its main function is to separate and select the characteristic wavelength spectrum of excitation light and emission fluorescence of substances in biomedical fluorescence inspection and analysis systems.The typical characteristics of fluorescence filters are deep cut-off depth, small autofluorescence, and good transmission surface shape, which is conducive to the extraction of fluorescence imaging. Therefore, a better fluorescent filter uses a single piece of colorless and transparent glass as the substrate, and coats the two surfaces of the glass.
Product Description: The molecule absorbs the excitation spectrum in the absorption band, and then emits a long-wave radiation spectrum in the emission band, which forms the fluorescence spectrum, which is the working principle of the fluorescence filter. In the field of analysis, fluorescence can be used for qualitative discrimination, quantitative analysis and real-time observation of biological and chemical activities. Due to its high sensitivity, good specificity, and simplicity, fluorescence filters are widely used in biological and analytical fields. The principle of fluorescence filter selection is to allow the fluorescence/emission light to pass through as much as possible at the imaging end, while completely blocking the excitation light to obtain the highest signal-to-noise ratio. Especially for the application of multiphoton excitation and total internal reflection microscopy, weak noise will also cause great interference to the imaging effect, so the requirement for signal-to-noise ratio is higher.
