New single instrument for Display Colour and Contrast Characterisation

The Photo Research 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 array detector spectroradiometer and PMT based photometer on the market.

It can be used either as a spectroradiometer or as a highly sensitive photometer. Additionally it can autoselect the most appropriate mode depending on the available light.

The unique design of the PR-680 makes tasks such as spectrally based colourimetry and high speed, low level luminance - required for display metrology - possible with a single instrument by supplying a wide dynamic range - 0.003 cd/m² (photometer and 1° aperture) to 2,200,000 cd/m² (spectral and 1/8° aperture) without using external neutral density filters.
