Fluorescence Filter
Fluorescence filters are key components in biomedical and life-science instruments. They separate and select the characteristic excitation and fluorescence-emission bands in biomedical fluorescence analysis systems. Daheng produces single- and multiwavelength fluorescence filters in volume, with high transmission and deep blocking to prevent other wavelengths from reaching the detector, ensuring bright images and a higher signal-to-noise ratio. They are used in PCR testing, gene sequencing, and biomedical fluorescence analysis requiring high resolution, including flow cytometers, PCR analyzers, and fluorescence microscopes, especially laser-excited fluorescence, fluorescence imaging, and high-resolution fluorescence systems. Innovative approaches and advanced coating processes, together with studies of commonly used reagents such as FAM, SYBR, VIC, HEX, JOE, TET, TAMRA, Cy3, ROX, Texas Red, CY5, and CY5.5, reduce multichannel fluorescence-test crosstalk to very low levels. A fluorescence-filter set generally consists of an excitation filter, an emission filter, and a dichroic mirror. The source ends with "The following are common wavelengths" without listing them in this text.
