Description
Middleton Spectral Vision offers the complete line of ImSpector™ Series imaging spectrographs for spectral imaging applications in both industry and scientific research. Spectrographs are complex optical components that change a camera to a hyperspectral imaging device with full contiguous spectral information and high spectral resolution. The spectrograph can be attached and integrated with a monochrome camera using a standard C- or U-mount to build a line imaging hyperspectral camera. The spectrograph may be integrated by the end-user. Alternatively, the integration along with alignment and calibration can be performed at Middleton Spectral Vision for an additional fee. Contact Middleton Spectral for more details.
ImSpectors V10H & V10
As with the visible range of spectrographs, there are two separate models for the standard VNIR spectrograph, the V10 for 2/3” sensors and the V10H for 1/2” sensors. For more information, go to the specifications tab.
