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.
