Input voltage is 120 VAC. It has 4 internal, selectable gratings with the following specifications.
Grating-1, 1200 g/mm, 750nm blaze
Grating-2, 600 g/mm, 400nm blaze
Grating-3, 150 g/mm, 300nm blaze
Grating-4, 150 g/mm, 800nm blaze
It appears that the gratings can be set to any wavelength value. However, the useable wavelength range is determined by the grating efficiency, being maximum at the blaze wavelength and decreasing away from the blaze wavelength. Thus, in addition to the VIS wavelength region, gratings 1 and 4 should get into the IR region and gratings 2 and 3 should go into the UV region.
