A specialty are the QuantaMAXTM series filters from Omega Optical, Inc. This series is based technically on dual magnetron reactive sputtering, DMRS, with optical monitoring. QuantaMAXTM series filters are generally hard coated, have steep edges, a high transmission rate with sideband suppression, and best imaging quality. In applications, this manifests itself in a high signal-to-noise ratio. QuantaMAXTM filters are available as fluorescence filter sets, single and multi-bandpass filters, beam splitters, and long-pass filters in the Vis and NIR range.
