X-Rite i1Pro

Low cost spectrophotometer (VPixx Edition)

The X-Rite i1Pro is the third generation of spectrophotometer from X-Rite. It is a true spectrophotometer, featuring greater accuracy than tri-stimulus photometers which are based on color filters. A new innovative Swiss-engineered design makes the i1Pro much more affordable than previous generations of spectrophotometers. The i1Pro is a contact spectrophotometer, and includes hardware for holding the sensor against the region of the display being calibrated.

The i1Pro connects to your computer over a USB interface, allowing your own software to initiate automated measurements and acquire data. The i1Pro can return CIE Lxy data for photometry measurements, and can also return raw spectral data between 380 nm and 730 nm in 10 nm steps for radiometry applications.

The i1Pro includes a calibration base allowing the photometer to be automatically recalibrated before each use.

GENERAL SPECIFICATIONS

  • Returns CIE Lxy coordinates and raw spectral data
  • Integration with VIEWPixx devices
  • USB powered
  • Low cost

VPixx Technologies offers a special edition of the i1Pro that includes custom software support for use with our displays. The i1Pro is compatible with our automated calibration tools, and we offer a custom MATLAB toolkit for manual calibration.

Please note that an i1Pro purchased directly from X-Rite, or a third party vendor, will not include these features.
