Abstract

The present invention relates to a method for producing narrow spectral linewidths more particularly by narrowing the full wave half maximum (FWHM) linewidth to a narrowed spectral linewidth. One of the advantages of the method of the present invention is to detect molecular bonding in analyte via contactless approach optical sensor. Another advantage of the present invention is that each LED has its own broader FWHM spectral linewidth and narrowing the linewidth to its unique and precise wavelength which contributes to more accurate observations and determination of analyte concentration.
