Imaging Spectrographs

Mid Wave Infrared Spectrograph

mid wave infrared spectrographThe mid wave infrared spectrograph is designed for the 3-5 µm range. It is intended to explore and remotely identify solids, liquids and gases in the C-H, O-H, N-H stretching vibration region. At this time, these spectrographs are available only for integration with certain camera types. For custom integration to your camera, please contact Middleton Spectral Vision.

For more information, including mechanical drawings, contact our application engineers.
