X-Rite i1Pro

Spectrophotometer

The X-Rite i1Pro 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 at 10 nm intervals for radiometry  applications.  The i1Pro includes a calibration base allowing the photometer to be automatically recalibrated before each use.

Software support includes a low-level ANSI C API, MATLAB/Octave and Python libraries for use under Mac OS X, Microsoft Windows, and Linux.
