Jasco V-670 UV-Vis Spectrophotometer

The V-670 double-beam spectrophotometer utilizes a single monochromator design covering a wavelength range from 190 to 2500 nm. The monochromator features dual gratings (automatically exchanged): 1200 grooves/mm for the UV/VIS region; 300 grooves/mm for the NIR region. A PMT detector is provided for the UV/VIS region and a Peltier-cooled PbS detector is employed for the NIR region. Both gratings and detector are automatically exchanged within the user selectable 750 to 900 nm range.
