An All-purpose Filter:
Progressive interference filters from schott are well-suited for use in areas such as analytic science, environmental analytics, biotechnology, genetic technology and fluorescence measuring applications. However, manufacturing these socalled »Veril« Filters requires specialized expertise in colored glass, as well as thin-film technologies, in order to allow various colors from the spectrum to be absorbed, reflected or permitted to pass through. In this way, the transmittance characteristics can be influenced to permit only defined wavelengths to pass through specific positions on the filter.
