Introduction
The PR-650 SpectraScan Colorimeter is a portable, battery-powered instrument designed for accurate spectral measurements. It is ideal for applications where portability, ease of use, and connectivity are essential.

Portability
The PR-650 is the only truly portable spot spectroradiometer, powered by a standard NiCad battery, making it suitable for remote measurements without an AC power source. It can be paired with a laptop using the optional SpectraWin software for a comprehensive measurement system.

Ease of Use
The device features Pritchard optics for easy target alignment and a simple point-and-shoot operation. Measurement results are displayed on a back-lit LCD screen.

Connectivity
Equipped with an RS-232 cable, the PR-650 can connect to various platforms (PC, Mac, Sun Workstation) and supports Remote Mode control language for integration with custom software applications.

SpectraWin Software
The optional SpectraWin software provides a graphical interface for control, display, and calculation, supporting automated measurement sequences and data export to other Windows applications.

Applications
The PR-650 is suitable for colorimetry in automotive/aerospace displays, textiles, printed samples, LED color measurement, and more.

Spectral Accuracy
Unlike filter-based instruments, the PR-650 measures optical radiation spectrally, ensuring accurate luminance and chromaticity results by calculating absolute intensity at each wavelength.

AutoSync Feature
The AutoSync feature adjusts exposure time to match the source refresh rate, ensuring accurate measurements of high-intensity sources like CRTs.
