The models are engineered to get no going elements or detector sockets, benefit from a ruggedized aluminum enclosure and an built-in A/D digitizer for unmatched durability and top quality that out performs any instrument in its course. A lot of versions give regular, concave grating, or substantial resolution (HR) optics for picked spectral ranges.
