Low-light level imaging techniques demand the ultimage in performance from a
filter set. Omega Opitcal's new, improved ALHPA VIVID filter sets are clearly the superior
choice for these applications.
Based on a proprietary deposition process, ALPHA VIVID filter sets feature the steepest
passband slopes in the industry. This means deeper blocking is achieved between
the exciter and emitter, which decreases background noise. Furthermore, the passbands
can be placed closer together while maintaining this deeper blocking. As a result, more
of the excitation and emission energy of the dyes are transmitted through the excitation
and emission filters, which helps to boost overall signal while keeping the noise
contribution to a minimum. Also, we have eliminated all autofluorescent absorption
glasses typically used in designing filters. The results of these improvements means
that these filters offer the brightest images on the market today.
