Ultraviolet antireflection coatings for use in silicon detector design.
We report on the development of coatings for a charged-coupled device (CCD) detector optimized for use in a fixed dispersion UV spectrograph. Because of the rapidly changing index of refraction of Si, single layer broadband antireflection (AR) coatings are not suitable to increase quantum efficiency at all wavelengths of interest. Instead, we describe a creative solution that provides excellent...
متن کاملDesign Multilayer Antireflection Coatings for Terrestrial Solar Cells
In order to analyze the influence of methods to design antireflection coatings (ARCs) on reflectivity of broadband solar cells, we provide detailed analyses about the ARC coupled with a window layer and the refractive index dispersion effect of each layer. By multidimensional matrix data simulation, two methods were employed to measure the composite reflection of a SiO2/ZnS double-layer ARC wit...
متن کاملFourier-transform method for the design of wideband antireflection coatings.
An iterative correction process, recently incorporated into the National Research Council of Canada Fourier-transform thin-film synthesis program, is applied to the design of wideband antireflection coatings. This type of problem is different from those solved in the past by this method. It cannot be handled in a practical way without a correction process. We consider in detail the effects-crit...
متن کاملAntireflection coatings with Chebyshev or Butterworth response: design.
There are several methods of designing an antireflection (AR) coating for a dielectric substrate of refractive index n by depositing one or more nonabsorbing films on it. For example, one approach' is to use only two materials in a coating but to vary the thicknesses of the layers to achieve a filter in which the radiant transmittance vs wavenumber simulates a Chebyshev function. Another approa...
متن کاملWitness sample preparation for measuring antireflection coatings.
Measurement of antireflection coating of witness samples from across the worldwide industry has been shown to have excess variability from a sampling taken for the OSA Topical Meeting on Optical Interference Coatings: Measurement Problem. Various sample preparation techniques have been discussed with their limitations, and a preferred technique is recommended with its justification, calibration...
