Meeting the Demand
|
|
Information display performance is continuing to improve at an almost exponential
rate. Of these improvements, one of the most important is luminance contrast. To
achieve improved contrast ratios, display manufacturers are striving to make black
blacker. In parallel with improvements in performance comes an increased level of
difficulty in measuring the ever decreasing luminance levels. The PR-810L is designed
to not only meet but exceed these demands.

Portability/Ease of Use
|
|
The PR-810L is unlike any of our previous photomultiplier tube (PMT)
based photometers - it's battery powered! The Lithium-ion battery
provides more than 12 hours of continuous operation providing the ultimate in portability.
It also features a full color touch screen display, and 75 mm objective
focusable from 14" (355 mm) to infinity.
Other hardware features include AutoSync® for automatically
synchronizing to the source refresh rate insuring the utmost accuracy, an External
Trigger Port allowing remote measurement activation from either a push
button or peripheral device, a Secure Digital (SD) port for measurement
storage.

Sensitivity
|
|
Using the largest of the 4 fully automated apertures, the PR-810L can measure 1E-6
(0.000001) footlamberts. A fully automated Neutral Density (ND) filter turret
provides 3 decades of filtration (10X, 100X and 1000X attenuation) resulting in
a 900,000,000:1 dynamic range in any aperture - wide enough for any contrast
measurement task. The total instrument dynamic range is 518 Billion:1

Connectivity
|
For help in communicating with the outside world, the PR-810L is supplied with a
USB interface and driver. The driver establishes a virtual COM port making
control of the PR-810L as easy as communicating over RS232. If a traditional RS232
interface is a must, it can be supplied to complement the USB I/F. Want
to go wireless? A Class 1 Bluetooth interface can be added for control of
the PR-810L up to 100 meters away.
For control of the PR-810L, an on-board protocol - Remote Mode Software - allows
you to make measurements and get the data you need by sending and receiving simple
ASCII text commands making integration into an ATE or other environment a snap.
