ULTRA Series HEX fluorescence filter set designed to provide a high signal-to-noise ratio of HEX probes contained in real-time qPCR samples when illuminated with an LED light source. This filter set is also ideal for use in a variety of fluorescence applications along with TAMRA, Alexa Fluor® 532, and all similar fluorophores. ULTRA Series filter sets provide better overall performance than our standard filter sets by using a combination of tight wavelength control (typically ± 1.5 nm), ultra-steep edges, deeper blocking, and the industry’s highest transmission levels. For fluorescence microscopy, they are also specified to produce zero pixel shift when filters are switched out in order to image multiple fluorophores in a single sample. All Alluxa optical filters are durable and hard-coated using our innovative SIRRUS plasma deposition process.
