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
acheive 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-805 is designed
to not only meet but exceed these demands. |

|
Portability/Ease of Use
|
|
The PR-805 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 |
|
|
Sensitivity
|
|
The PR-805 can measure down to 9E-4
(0.0009) footlamberts. A fully automated Neutral Density (ND) filter turret provides
3 decades source attenuation (10X, 100X and 1000X attenuation) resulting in a 9 Million : 1
dynamic range in any aperture - wide enough for any contrast measurement task. |

|
Connectivitiy
|
|
For help in communicating with the outside world, the PR-805 is supplied with a
USB interface and driver. The driver establishes a virtual COM port making control
of the PR-805 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-805 up to 100 meters
away. For control of the PR-805, 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. |
