Lab, Field & Factory Flexibility
|
|
The Pritchard™ PR-880 is the first fully automatic filter photometer, A culmination
of Photo Research's technical innovation and excellence, the PR-880 is ideal for
today's automated factory and ATE/OEM environments.
With an all-in-one, compact design, and weighing only 9.4 lbs, the PR-880 also delivers
benchmark performance in traditional lab, field and factory applications.
|
|
|
Automated Ease & Precision
|
|
The PR-880 is designed for flawless precision and exceptional ease of use. Every
function including multiple-mirror aperture positioning, dual filter wheels, detector
zero and viewing system shutters are automated with precise motorized controls.
Onboard microprocessor control - a powerful 16-bit, on-board microprocessor controls
all mechanical components, measurements and calculations. Results displayed on the
4 x 20 character backlit Liquid Crystal Display (LCD) enable at-a-glance analysis.
Automatic internal calibration - the PR-880 features automatic calibration using
an optically-regulated internal calibration source. The stability of this internal
source assures you the utmost accuracy and repeatability.
Built in memory, Save & Restore - the PR-880 stores all operating software,
calibration factors, and up to 100 measurements on an internal 512K Integrated Circuit
Memory (ICM) card. Standard Save/Restore software and the RS-232 interface support
contingent data, software, and calibration factor recovery.

|
Enhanced Sensitivity
|
|
An ultra-sensitive photomultiplier tube (PMT) is featured in the PR-880 enhanced
by four ranges of electronic gain (1X, 10X, 100X and 1000X) and four internal neutral-density
attenuation filters (10X, 100X, 1000X and 10000X) yielding eight decades of dynamic
range for each aperture.
Automatic signal interaction - for extremely low-level measurements, the PR-880
automatically integrates the PMT signal - making it the most sensitive filter photometer
in its class.

|
|
Push-Button & Remote Operation
|
|
Measure light, color and brightness with push-button ease and accuracy. With eight
on-board backlit controls you can actuate every measuring function and every software
menu - in seconds.
Remote Mode software - offers easy programming using American Standard Code for
Information Interchange (ASCII) commands. All hardware, measurements, data transfer
and file operations can be remotely monitored and controlled from any PC (or Macintosh),
Mini or Mainframe in any OEM, CAM or ATE environment.
|
|
|
Alignment Certainty
|
|
Pritchard™ optics provide superior, non-ambiguous target alignment. Here the
measuring aperture, centered in the user's 8.5° field-of-view, and the alignment
aperture are one and the same. A 100% non-polarized optical path means even polarized
sources, such as LCDs, are measured accurately.
|
|
|
Range & Visibility
|
|
The PR-880's range and versatility make it an exceptional value. Variable apertures
and the MS-55 objective lens accommodate virtually any target size. For target sizes
down to 0.001mm, a variety of microscopic objective lenses are available.
|
|
|
Assured Accuracy
|
|
Photo Research instruments meet the highest standards of quality and accuracy. Case
in point: The PR-880's photopic filter is hand trimmed to precisely match the eye's
daylight adapted response from 380 nm to 780 nm. Thus, the PR-880 provides the right
answer regardless of the source spectral distribution.
|
|
|
Best in it's Class
|
|
For the versatile light measurement solution offering unparallel accuracy, precision,
and ease-of-use in one, compact, ergonomic package, the Pritchard™ PR-880
filter photometer is clearly the best in its class.
