Near infra red and visible spectrum transparent coatings.

Deposition Sciences : 06 March, 2008  (New Product)
Lens coatings from Deposition Sciences provide transparent conductivity for lenses designed for the visible spectrum and near IR.
Deposition Sciences announces a line of transparent conductive coatings for use in the visible and near-infrared (NIR) spectral ranges. The new family of transparent coatings is compatible with DSI's dichroic filter technology, enabled by the patented Microdyn sputtering process. This proprietary technology yields high performance, highly uniform, transparent conductive filters that remain extremely stable while withstanding high thermal loads and changes in humidity.

DSI offers a wide variety of optical thin films that operate in the visible and near-IR wavelengths. These can now be combined with the new transparent conductive coatings and formulated to be broadband or spectrally selective, per customer requirements. The new conductive coatings with indium tin oxide, induced transmission silver, and induced transmission gold, all deliver high transmission within selected wavelength ranges from 400 nm to 2500 nm. These coatings can be applied onto a wide variety of substrates, including silicon, germanium, zinc sulfide, zinc selenide, and most glass types that are compatible with the visible to near-infrared spectral regions.

The new visible and NIR transparent conductive filters are ideal for a variety of tasks, from anti-static applications with sheet resistances of megaohms per square, to EMI shielding with sheet resistances as low as a few ohms per square. DSI also offers an extensive array of in-house metrology and environmental analysis equipment for product characterization and testing for coatings manufactured at DSI and for coatings and materials produced by external vendors. These test and measurement capabilities assure quality that meets or surpasses many of the military standards for high performance and coating durability in extreme conditions.
