A multimedia catalog titled “Precision Optical Filters for Fluorescence Microscopy” has been released by !%Omega Optical Inc.%! on compact disc. It introduces the QuantaMax line of stable, durable, high-signal-to-noise sets, and new filter sets for fluorescent protein and FRET applications, complementing a variety of dye-specific sets for single- and multilabel microscopy applications. The catalog includes an image gallery, live-cell movies, fluorescence image screen savers and links to Web tools such as the Curvomatic database of fluorophores and filter spectra, and the Build-A-Filter specification and quoting tool for custom filters. Application notes, a fluorophore reference table, and light source and detector spectral data also are provided.
