Imaging Spectrographs

eNIR Spectrograph

Extended NIR spectrograph for near infrared spectroscopy imaging (1)This extended near infrared imaging spectrograph supports a large spatial image size for sensor sizes up to 18 mm. The V16M has an extended operating range of 600 to 1600 nm, providing new possibilities for hyperspectral imaging applications in vegetation, food, and semiconductors. Due to the larger format and the unique optical design, the light throughput of the V16M is superior to the Standard or Enhanced Series spectrographs, allowing for an even higher signal-to-noise ratio.

At this time, this spectrograph is available only for integration with certain camera types. For custom integration to your camera or for more information, please contact our application engineers.
