Abstract

Described herein are spectrometers comprising one or more wavelength-selective filters, such as guided mode resonance filters. Some of the spectrometers described herein are configured for obtaining absorbance spectra in a discrete fashion by measuring absorbances of a sample at multiple discrete wavelengths or wavelength bands. In another aspect, methods are also provided for obtaining spectra, images and chemical maps of samples in a discrete fashion.
