Abstract:
A noninvasive analyzer apparatus and method of use thereof is described using a plurality of time resolved sample illumination zones coupled to at least one two-dimensional detector array monitoring a plurality of detection zones. Control of illumination times and/or patterns along with selected detection zones yields pathlength resolved groups of spectra. Sectioned pixels and/or zones of the detector are optionally filtered for different light throughput as a function of wavelength. The pathlength resolved groups of spectra are subsequently analyzed to determine an analyte property. Optionally, in the mapping and/or collection phase, incident light is controllably varied in time in terms of any of: sample probe position, incident light solid angle, incident light angle, depth of focus, energy, intensity, and/or detection angle. Optionally, one or more physiological property and/or model property related to a physiological property is used in the analyte property determination.

An anti-reflective coating film is formed from a coating solution composition that includes a silane-based precursor. When measured via Fourier Transform Infrared (FT-IR) Spectroscopy using a wavelength of 1064 nm, the coating solution composition exhibits a peak intensity ratio IB/IA and a peak intensity ratio IC/IA of equal to or greater than 0.47, respectively. The peak intensity IB is in a range of about 930 cm−1 to about 960 cm−1, the peak intensity IA is in a range of about 1110 cm−1 to about 1130 cm−1, and the peak intensity IC is in a range of about 1020 cm−1 to about 1050 cm−1. A solar cell including the anti-reflective coating film, and a method of predicting the strength of the anti-reflective coating film for the solar cell have been disclosed.
