Abstract (en)
[origin: WO0146659A1] Low cost and form factor spectrometers are disclosed. A spectrometer comprises a substrate, a plurality of optical sensors (979), a plurality of spectral filters (977), an optical manifold (976) and one or more processing elements (980). The plurality of spectral filters (977) and the one or more processing elements (980) are mounted on the substrate. The spectral filters (977) are fixedly positioned over at least a group of the optical sensors (979) and fixedly positioned with respect to the substrate. An optical manifold (976) is fixedly positioned over the spectral filters (977). The optical manifold (976) has a plurality of exit ports and an entrance port, wherein light entering the entrance port is transmitted to an interior portion of the optical manifold (976) and a portion of the light is transmitted from the exit ports through some of the spectral filters (977). The spectrometers are disclosed embedded in printing and scanning devices, computer companion devices, scope-type devices and the like.
