Unique Design
|
The PR-680L 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-680L 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-680L 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-680L 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-680L displays data and color spectral graphs on the system
display. The PR-680L design provides stand alone operation - no PC required. The
PR-680L can also be controlled via the world famous SpectraWin™
2 software over the USB, RS232(optional)
or Bluetooth (optional) interface.

Flexibility
|
The unique design of the PR-680L 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 - 0.00007 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 the spectroradiometer and photometer, no realignment of
the instrument to the target is required when switching between modes.
An optional analog output provides the capability of using the PMT as a high speed
tool for characterizing display ON / OFF response (3 µsec response)
or waveform analysis of flash sources. We've further enhanced the flexibility by
adding two sensitivity modes (Standard & Extended) and 4 measurement speeds
: Normal, Fast, 2X Fast, 4X Fast.
For applications other than luminance, the PR-680L 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-680L also provides the capability for interactive display white point calibration
(RGB Software).

Connectivity
|
|
It's easy for the PR-680L 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.
