Omega-Optical_cd_cover.gifA multimedia catalog on CD has been released by Omega Optical Inc. Titled “Precision Optical Filters for Fluorescence Microscopy,” the disc 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 screensavers and links to Web tools such as the Curv-o-matic database of fluorophores and filter spectra, and the Build-a-filter specification and quoting tool for customization. Application notes, a fluorophore reference table, and light source and detector spectral data also are provided.

1. With respect to radiation, a device used to attenuate particular wavelengths or frequencies while passing others with relatively no change. 2. See digital filter.
fluorescence microscopy
Observation of samples using excitation produced fluorescence. A sample is placed within the excitation laser and the plane of observation is scanned. Emitted photons from the sample are filtered by a long pass dichroic optic and are detected and recorded for digital image reproduction. 
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
