The Stabilife patented interference filter manufacturing process used by the Corion Filter division of Newport provides superior performance, extremely economically
Interference filters must be able to deliver repeatable and accurate wavelength vs transmission response, regardless of the operating conditions.
In demanding applications such as fluorescence detection, wavelength stability is absolutely critical to ensure dependable results.
Spectral shifts in the range of 2-5% of wavelength are typical of interference filters manufactured with un-stabilized metal oxide coatings when affected by moisture.
Stabilife filters typically exhibit total wet-to-dry shifts of less than 0.02% of wavelength.
Stabilife optical filters and coatings are manufactured using two patented processes for the deposition of metal oxide thin film optical coatings; reactive ion plating (RIP) and hybrid plasma deposition (HPD).
Both processes yield highly dense, thin film coatings with extraordinary hardness, abrasion resistance, and adhesion to the substrate.
Stabilife thin-film optical coatings have demonstrated excellent resistance to damage due to handling, extreme nuclear and optical radiation, and severe environmental conditions.
In the most severe applications, such as autoclave immersed nuclear reactor monitoring, Stabilife filters have demonstrated spectrally stable performance lifetimes exceeding 8000 hours.
Stabilife filters have been qualified for telecommunications applications per the requirements of Telcordia GR-2883.
While most applications are much less demanding than these, the same robust coatings as are required for extreme applications, are routinely supplied for all Stabilife products Stabilife films are typically five to ten times less sensitive to thermal variation than un-stabilized metal oxide and therefore provide maximum spectral stability for all types of precision coatings including bandpass, dichroic, edge, notch and polarizer coatings.
Stabilife films are produced over the wavelength range from 200nm in the UV to 3microns in the IR and have been utilised in a wide variety of applications.
