HB Optical can provide high-performance fluorescent filters for PCR detection, suitable for various fluorescent PCR detectors. Plasma-assisted deposition process (PIAD) and ion-beam-assisted deposition process (IAD) are used to manufacture these filters to ensure that the filters have a long service life and stable spectral performance. HB Optical uses independent design and manufacturing, cooperative design and production and OEM methods to provide high-performance fluorescent optical filters for domestic and foreign customers. Innovative methods combined with advanced coating process through the study of common reagents such as "FAM, SYBR, VIC, HEX, JOE, TET, TAMRA, Cy3, ROX, TexasRed, CY5", etc., to achieve the crosstalk coefficient of multi-channel fluorescence test Reduced to an extremely low ideal level.
