A video photometer differs
from traditional photometers by utilising a multi-element, two-dimensional
detector - most typically, a CCD. This gives the video photometer
the ability to take a "snapshot" of the target and then
perform photometric analysis of the captured image. Tasks such as
display uniformity can be completed in a fraction of the time with a
video photometer in place of a more traditional instrument because
several "measurements" can be performed simultaneously on a
"spot" photometers, the detector spectral response of Video
Photometers is filtered to match the CIE Photopic response function
for accurately weighted photometric measurements.
Research developed the first commercially available video photometer
over 15 years ago. We are proud to introduce our newest and most
advanced video photometer - the PR-920
Digital Video Photometer (DVP). The heart of the new PR-920 is a
thermoelectrically cooled, scientific grade 1024 x 1024 element
digital CCD camera which helps to make it the most accurate,
sensitive and repeatable video photometer in its class.
is the low cost solution to your CCD photometer applications and
features many of the same capabilities of the PR-920 at a fraction of
the price. The PR-905 provides high accuracy photometric and spatial
measurements while staying within today's shrinking budgets.
