Performance and application of a new planar array infrared spectrograph operating in the mid-infrared (2000-975 cm(-1)) fingerprint region.

A no-moving-part planar array infrared spectrograph (PA-IR) equipped with a 256 x 256 mercury cadmium telluride (MCT) focal plane array has been designed and constructed. The performance of the instrument, whose frequency range extends from 2000-975 cm(-1), has been assessed in terms of resolution, bandwidth, and signal-to-noise ratio. The PA-IR… CONTINUE READING
