Midsummer AB [2] (Swedish manufacturer of CIGS solar modules and sputtering equipment for thin-film solar cells) Sunflare [3] Sunplugged [4] Solar Cloth [5] Former companies or companies that no longer produce CIGS modules: IBM; International Solar Electric Technology; Flisom (founded in 2005 as a spin-off company of ETH Zürich, Switzerland)
The effects of thin-film interference can also be seen in oil slicks and soap bubbles. The reflectance spectrum of a thin-film features distinct oscillations and the extrema of the spectrum can be used to calculate the thickness of the thin-film. [1] Ellipsometry is a technique that is often used to measure properties of thin films. In a ...
An interference filter consists of multiple thin layers of dielectric material having different refractive indices. There may also be metallic layers. There may also be metallic layers. Interference filters are wavelength -selective by virtue of the interference effects that take place between the incident and reflected waves at the thin-film ...
Thin-film optics is the branch of optics that deals with very thin structured layers of different materials. [1] In order to exhibit thin-film optics, the thickness of the layers of material must be similar to the coherence length ; for visible light it is most often observed between 200 and 1000 nm of thickness.
RIGOL was founded in Beijing in 1998 and released its first product, a high-performance virtual digital storage oscilloscope, in May 1999. [1]In 2018 the company released the new RSA5000 real-time spectrum analyzer and the MSO7000, as well as MSO5000 series, based on the new ASIC based Ultravision-II platform.
Secondary-ion mass spectrometry (SIMS) is a technique used to analyze the composition of solid surfaces and thin films by sputtering the surface of the specimen with a focused primary ion beam and collecting and analyzing ejected secondary ions.
In 2002, Aeroflex acquired IFR Systems Inc, a test equipment manufacturer from Wichita, Kansas, originally founded in 1937. [6] In 1998, IFR previously acquired Marconi Instruments, a British test equipment manufacturer. [7] In 2007, Aeroflex was taken private by a group of private equity firms including Veritas Capital, Golden Gate Capital, GS ...
Alternately, dichroic filters (also called "reflective" or "thin film" or "interference" filters) can be made by coating a glass substrate with a series of optical coatings. Dichroic filters usually reflect the unwanted portion of the light and transmit the remainder. Dichroic filters use the principle of interference. Their layers form a ...
