Unique Design
|
The PR-680 SpectraDuo marks the beginning of a new era in light measurement. This
unique patent pending, battery powered portable instrument is the first and only
combined fast-scanning 256 detector element spectroradiometer and PMT based photometer
on the market. The PR-680 has three available operating modes
- A fast scanning spectroradiometer (like the PR-655)
- A highly sensitive photometer (like the PR-880)
- Auto Select mode which automatically selects between detectors based on the available
signal.
The PR-680 is supplied with 4 automated measuring apertures (1°, ½°,
¼° and 1/8°) and an automated measure shutter. Other hardware features
include AutoSync® for automatically synchronizing to the source refresh
rate insuring the utmost accuracy, a Secure Digital (SD) port for measurement storage,
an external trigger port allowing remote measurement activation from either a push
button or peripheral device, and a long lasting rechargeable Lithium-Ion (Li-Ion)
battery. |

Easy to Use
|
|
The PR-680 is controlled via the on-board, 2.25" x 3" high resolution, full color
touch screen LCD display and 5-way navigation keypad for easy navigation. Following
a measurement, the PR-680 displays data and color spectral graphs on the system
display. The PR-680 design provides stand alone operation - no PC required. The
PR-680 can be also controlled via the world famous SpectraWin™
2 software over the USB or Bluetooth interface. |

Flexibility
|
The unique design of the PR-680 makes tasks such as spectrally based colorimetry
and high speed, low level luminance - required for display metrology - possible
with a single instrument by supplying a wide dynamic range - 0.003 cd/m² (photometer
and 1° aperture) to 2,200,000 cd/m² (spectral and 1/8° aperture) without
using external neutral density filters. Since the Pritchard® viewing and measuring
optics are shared by both detectors, tests can be performed without requiring realignment.
Provides the capability of using the PR-680 as a high speed optical input (PMT signal)
to a device such as an oscilloscope. The bandwidth is approximately 20 µsecs. Useful
for tasks such as ON/OFF or gray level response time for LCD's. Includes a connector
on the PR-680 and interconnecting cable. We've further enhanced the flexibility
by adding 2 sensitivity modes (Standard & Externded) and 4 measurement speeds
: Normal, Fast, 2X Fast, 4X Fast.
For applications other than luminance the PR-680 can be supplied with optical accessories
such as a cosine receptor for illuminance, LR-127 LED Analyzer
for testing LED's to CIE 127, fiber probe for remote non-line-of-sight testing,
and a series of magnification lens for small spot size analysis. An RGB otpion is
available that provides an interactive method for display white point calibration
based on spectral measurements.

Connectivity
|
|
It's easy for the PR-680 to talk to the outside world - it comes equipped with USB
and (optional) Bluetooth® wireless interfaces.
It is supplied with text based, Remote Mode syntax and a driver that emulates an
RS-232 interface (COM: port) making it a simple task to generate custom programming
to perform specific tasks or for inclusion in an ATE environment. If needed, an
RS-232 interface can be added to complement the standard USB. |
