Spectra is proud to announce the introduction of the new PR-650 RGB
Colour Analyser from Photo Research. The PR-650 RGB has been created
to provide a spectrally based solution for the white point
calibration of CRTs, LCDs and digital projectors. It builds on the
established PR-650 spectroradiometer and the acquisition of complete
spectral data giving you the distinct advantage over existing filter
instruments, since there are no errors due to filter mismatch.
It can be used to
calibrate displays in one of two modes - a learn mode or by entering
target chromaticity and luminance values. A graphic interface
provides an easy method for adjusting the RGB levels to the desired values.
In addition to the new RGB
capabilities, the PR-650 RGB system can be used to make direct
measurements of luminance, CIE Chromaticity (1931 xy and 1976 u'v')
and correlated colour temperature. The standard PR-650 measurements
such as L*a*b*, L*u*v*, DE*, DY, xy, DYu'v' and DCCT are available
using either PC based SpectraWin software, or directly on the
instrument using an optional PR-650 RAM card.
