Home Products Imspector Spectrographs Visible Near Infrared Light (VNIR) 400-1000 nm
ImSpector for VNIR (400-1000 nm) - high performance, cost effective integration

Specim ImSpectors designed for the VNIR (400-1000 nm) wavelength ranges. These spectrographs provide a straightforward, high performance yet cost-effective method of integration. When combined with scientific grayscale CCD or CMOS cameras, the combination provides a line-scan Spectral Imaging Device.
