spectroradiometers are designed to measure the absolute spectral
quantity, in terms of power, of the light under test by breaking up
the broad band incoming optical signal into its component parts by
means of a diffraction grating - much like a prism. The diffracted
light is then imaged onto a multi-element detector. Each detector
element in turn samples its own part of the diffracted spectrum. In
addition to the measured spectral data, luminance, CIE chromaticity
values, reflectance and transmittance are readily obtained from the
spectroradiometers are designed to measure radiance
(watts/steradian/square meter) utilising the patented Pritchard
optics to collect the incoming optical radiation. Their ease-of-use,
accuracy and reliability has made this product family the most widely
used. Our spectroradiometers are tailored for display measurement,
but can be outfitted to address virtually any light measurement application.
PR-670 / PR-680
PR-670 SpectraScan is the newest addition to the world renowned
SpectraScan colourimeter series of instruments. This unique, portable
battery powered instrument utilises a fast-scanning 256 detector
element spectometer and is supplied with automated measuring
apertures and automated measure shutter.
The PR-680 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.
battery-powered portability, ease-of-use, connectability and
spectrally accurate measurement results are important criteria when
selecting a photometer or colourimeter, the PR-655 SpectraScan®
is the instrument of choice.
