Ann Arbor Sensor Systems is developing and experimenting with a Long Wave Multispectral Diffractive Optic Imaging Spectrometer that operates in the 7 to 14 micron band. The instrument currently under development is for fixed mount applications. The focal plane is an uncooled 320 x 240 30 micron pitch amorphous silicon microbolometer array. With a spectral bandwidth of 220nm the unit is capable of resolving moderate to broad spectral features. This paper will describe the physical characteristics and characterization of the experimental device. Design trades and test data will be presented.
