Abstract
A spectrometer (2500) including a detector integrated circuit (2501) which includes a linear array (2503) of 128 adjoining 2 by 10 superpixel bolometers in a package base (2530) and under an infrared transparent lid (2510) with a graded interference filter (2511). Filter (2511) has a rectangular shape and is a passband filter with a center wavelength which varies linearly along the direction of the long sides which is also the long direction of the linear array (2503) of bolometers. The center wavelength varies by a factor of about 2 over the length of the linear array (2503).
