The ImSpector Series offers several visible spectrographs. These spectrographs permit straightforward and cost-effective integration. A visible spectrograph combined with a scientific grayscale CCD or CMOS camera produces a high performance line-scan hyperspectral spectrophotometer for visible spectroscopy imaging.
Visible spectrograph series: Standard and Enhanced. The Enhanced Series offers the best optical performance, and is recommended for high resolution (< 3 nm) applications.
There are two separate models for the standard VIS spectrograph, the V8 for 2/3” sensors and the V8H for 1/2” sensors. Both of these models share the same mechanical characteristics.
The E-Series model is available for VIS imaging applications that require higher spectral or spatial fidelity.
