Applications
In biological fluorescence imaging, LP490nm longwave pass filters are often used to filter out short-wavelength excitation light and allow only fluorescent emission light to pass through, thereby enhancing the detection effect of fluorescent signals. This allows researchers to observe fluorescent markers in biological samples more clearly and then analyze the distribution, localization and interaction of biomolecules.
In optical instruments, such as microscopes and spectrometers, LP490nm longwave pass filters also play an important role. It can help researchers accurately select the required wavelength range, thereby achieving the extraction and analysis of specific optical signals. This is of great significance in fields such as optical measurement, material detection and scientific research.
