The PR-650 SpectraColorimeter is the latest in the Photo Research family of SpectraScan
fast scanning instruments. It's the only truly portable, spectrally-based
luminance telephotometer/colorimeter. Complete, NIST-traceable photometric and colorimetric
measurements are performed spectroradiometrically. And, this hand-held portable
overcomes the spectral errors inherent in filter instruments.

The right instrument
|
|
When battery-powered portability, ease-of-use, connectability and spectrally accurate
measurement results are important criteria when selecting a photometer or colorimeter,
the PR-650 SpectraScan is the instrument of choice. |
|
|
|
Battery powered portability
|
|
The PR-650 is the only truly portable spot spectroradiometer available. The standard
NiCad battery makes the PR-650 ideal for making measurements in remote areas where
an AC power source is unavailable. Combine this portability with a laptop running
the optional SpectraWin™ Windows®
based software, and you have a full-featured measurement system that can be transported
in your briefcase. |
|
|
|
Ease of use
|
|
The PR-650 is as easy to use as point-and-shoot. The world famous Pritchard®
optics make target alignment as easy as aim/focus/shoot. When you are ready to make
a measurement, simply press the measure button. The results are displayed on the
backlit 4 x 20 character LCD display. |
|
|
|
Connectability
|
|
Each PR-650 is equipped with an RS-232 cable that lets you link to the outside world
from just about any platform (PC, Mac, Sun Workstation etc.). We've also included,
as standard equipment, Remote Mode control language. This simple to use text based
language lets you make measurements with the PR-650 and retrieve calculated measurement
results - all from your custom software application (e.g. Visual C++, Visual Basic
etc). |
|
|
|
SpectraWin™ software
|
|
For an easy-to-use, graphics based link to the PR-650, the optional Windows®
('98, 2000 or XP) SpectraWin™ software
package provides a fully functional control, display and calculation platform. Features
such as automated measurement sequences (reflectance, transmittance etc.), go/no
go color measurements and a built in macro recorder make your measurement task as
easy as click and go. After the measurement, cut-and-paste data tables or graphics
displays (e.g. spectral or CIE charts) to other Windows applications. |

|
|
Spectral Accuracy
|
|
Unlike other instruments in its price range, the PR-650 measures optical radiation
spectrally instead of relying on filter technology. To accurately deliver important
measurement results such as luminance and chromaticity - the PR-650 determines these
parameters by measuring the absolute intensity at each wavelength, then calculating
the appropriate CIE value. So, regardless of the source, the result is accuracy
time after time after time. |
|
|
|
AutoSync®
|
|
The built-in AutoSync® feature takes the worry out of accurately measuring
high intensity refreshing sources such as CRT's by adjusting the exposure time to
the source refresh rate - and simultaneously reports the refresh rate of the source.
