The **OPTOStokes CY5 Fluorescence Filter Set** is engineered for superior signal resolution in the deep red to Near-Infrared (NIR) spectrum, crucial for multiplexing assays in qPCR, flow cytometry, and advanced imaging. Optimized for the CY5 fluorophore, this set delivers high transmission efficiency and exceptional blocking (Optical Density > 6), effectively isolating the target signal from background noise and unwanted excitation energy.
Technical Specifications for High-Contrast Performance
Each filter is fabricated using high-stability thin-film coatings, offering precise spectral control for demanding medical and research instrumentation.
