UV-VIS-NIR spectrophotometer

It is a double beam, double monochromator, ratio recording UV/Vis spectrophotometer with microcomputer electronics, controlled by a personal computer. All reflecting optical system (SiO2 coated) with holographic grating monochromator with 1440 Lines/mm UV/Vis blazed at 240 nm, Littrow mounting, sample thickness compensated detector optics. The optical source and detector are a pre-aligned tungsten-halogen and deuterium and R955 Photomultiplier, giving high energy throughout the whole UV/Vis range respectively.

System capabilities:

  • Wavelength Range: 190 nm - 3300 nm

  • Wavelength Resolution: UV/Vis Resolution ≤ 0.17 nm, NIR Resolution ≤ 0.20 nm

  • Source: Pre-aligned tungsten-halogen and deuterium

  • Detector: Photomultiplier R955 for high energy in the whole UV/V is wavelength range. Peltier cooled PbS detector for NIR.

  • Wavelength Reproducibility: UV/Vis (Deuterium Lamp Lines) ≤ 0.06 nm, NIR (Deuterium Lamp Lines) ≤ 0.1 nm

  • Photometric Range: 6 A (using reference-beam attenuation)

  • Photometric Display: Unlimited
