The CGS contains an optical port, an imaging grating and a CCD detector. The core of the spectrometers is a blazed, flat-field grating for light dispersion and imaging. The CCD detector has an electric-shutter function that enables minimal integration times.
- High sensitivity and resolution
- Very good signal-to-noise ratio and high dynamic range
