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°, 0.5°, 0.25°
and 0.125°) 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 also be 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 - 0.001 fL (photometer
and 1° aperture) to 5,000,000 fL (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.
PProvides 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 & Extended) 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 lenses for small spot size analysis. The PR-680 also
provides the capability for interactive display white point calibration (RGB software).

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.
