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.
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 and automated with precise
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
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-32 interface support contingent data, software, and
calibration factor recovery.
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
integrated the PMT signal - making it the most sensitive filter
photometer in its class.
& Remote Operation
Measure light, colour 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 use 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.
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-polarised optical
path means even polarised sources, such as LCDs, are measured accurately.
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.
Photo research instruments
meet the highest standards of quality and accuracy. Case in point:
The PR-880's photopic filter is designed to precisely match the eye's
daylight adapted response from 380 nm to 760 nm. Thus, the PR-880
provided the right answer regardless of the source spectral distribution.
in its Class
For the versatile light
measurement solution offering unparalleled accuracy, precision, and ease-of-use
in one, compact, ergonomic package, the Pritchard PR-880
filter photometer is clearly the best in its class.
