UVIKON XS Spectrophotometer

Routine Power in UV/Vis Spectroscopy

The UVIKON Simplicity Concept represents the first Spectrophotometer Series featuring Advanced Digital Signal Processing Technology. ADSP ensures reliable data acquisition, a superb sensitivity level to allow linear measurements even at high OD values, and a very low instrument noise. Uvikon XS in combination with the easy to use Windows compatible LabPower Junior software package supports the entire range of daily routine applications.


  • 100% symmetric true double beam technology for high data precision and stability
  • Rotating Mirror (Chopper) System to achieve reliable data even in concentrated samples

Sample Compartment

  • 140 mm depth, 332 mm width, 162 mm height, with 120 mm beam separation
  • Total and easy access: front top and back covers are quickly removable
  • Three point positioning of accessories for high reproducibility of results
  • Quartz windows at the beam entrance and exit to the sample compartment prevent the optics from being contaminated

Optical Design

  • Well proven true symmetric double beam optics with only 6 reflecting surfaces per beam
  • High-Energy diffraction Zeiss™ Monochromator Design using a holographic blazed grating with 1300 lines per mm
  • Very sensitive photodiode with a rotating all-reflective chopper mirror providing 100% energy in sample and reference beams plus dark current correction
  • External source bench providing thermal insulation with optical bench and isolation of the whole photometric assembly against contamination by ozone emitted by deuterium lamp
  • Optical bench base manufactured to a tolerance of 0.01 mm in 1 meter
  • Complete optical system sealed against atmospheric contamination from dust and volatile compounds
