Spex 1404 Spectrometer with Monochromater Control Unit and Power Supply. This is a very versitile modular system and has lots of accessories and features included and available.
Optical design combines unsurpassed luminosity, stray-light rejection, resolution and spectral coverage. Interchangeable gratings permit operation from UV through far IR. Side and front exit ports allow easy switch from single-channel (photomultiplier) to multichannel (photographic, TV, diode array) detection. Side and front entrance slits facilitate comparison of two sources. Vibrating mirror attachment permits monitoring of transients and reactions. Typical Applications: Raman and other frequency shifted scattering. High Resolution luminescence (excitation and emission), plasma analysis for vanishingly low traces of elements, time resolved studies (scattering and luminescence). This unit come with TWO gratings installed: Spex 1800 gr./mm./H -- 294 Blaze Please refer to the photoset for close-up pictures Mount: Modified Czerny-Turner, additive dispersion Focal Length: 0.85m Aperture: f/6.9 Mirrors: Aluminized MgF2 overcoat optimized for 500 nm Ruled Gratings: Area, mm: 110 x 110 / 110 x 128 Density, grooves/mm: 30-3600 Blaze, nm: 200-30,000 Holographic Gratings: Area, mm: 110 x 110 / 110 x 128 Density, grooves/mm: 1800, 2400, 3600 Range: UV or Visible Spectral Coverage: 175-1040 nm Dispersion at 514.5nm: 0.31 nm/mm Resolution, Hg 579.1 nm (FWHM): .005nm Multi-channel Coverage mm: 25 Accuracy:
