Model 2062 Spectrometer

Model 2062 Two meter Czerny-Turner high resolution scanning monochromator, manual drive with wavelength counter. (Select high resolution Stepper Wavelength Drive System). This monochromator has an effective aperture of f/17.2 and comes entrance complete with the following:

• Bilateral and exit slits, continuously adjustable from 5 to 4000 mm. Height adjustable to 20 mm., includes manual shutter.
• Collimating and focusing mirror assemblies. A1 and MgF2 coated is standard. For I.R. application Au (Gold) coated collimating, focusing mirrors and gratings can be supplied.
• "SNAP-IN" grating holder (US pat. # 3433557) to accept 120 x 140 mm and 110 x 110 mm plane gratings.
• Two grating positions, 0° to 50° and auxiliary 20° for echelle gratings and wavelength range extension.
