Abstract
Spectrometer designs are provided. The spectrometer includes two planar diffraction gratings disposed in a cascade, without intervening optics therebetween. Advantageously, the described configurations may promote both a high throughput and a high resolution, enabling the design of a portable device having sufficient resolution for on-site use or in the laboratory. In some implementations, two different secondary diffraction channels may be provided.
