About This Product

■Summary

This is a spectroradiometer that specializes in a wide dynamic range from black to white. Achieves wide dynamic range measurement without changing the measurement angle (aperture) or adding a neutral density filter. In addition, it is a top model among spectroradiometers, and its measurement speed and accuracy are top class. Optional built-in rechargeable battery and half-width switching function are available.

■Features

This is a spectral radiance meter specialized for measuring display contrast. Achieves a dynamic range of 1,000,000:1. In addition, it is a top model among spectroradiometers, and its measurement speed and accuracy are top class. ・No need to switch the aperture or install a neutral density filter Example) 2° aperture measurement range 3.42×10-5 to 1.71×104cd/m2 ・High-speed and high-precision measurement using 512 array sensors ・Up to 8 types of measurement angles (apertures) can be installed to support various measurement spot sizes. ・High-precision measurement of wavelengths with laser-like peaks is possible with the half-width switching function. ・With built-in rechargeable battery, the measuring device itself can be used independently. ・AutoSync function that synchronizes to the frequency of the measurement target (20 to 2,000Hz) ・With a wide range of optical accessories, measurement of units other than luminance is possible. ・Dedicated software and command control

■Measurable units

Brightness, radiance, chromaticity, color temperature, illuminance, irradiance, luminous intensity, radiant intensity, total luminous flux, radiant flux, transmittance, reflectance

■Accessories

・Radiance and brightness accessories: objective lenses, fiber probes ・Intensity and luminosity accessories: LED receptors ・Irradiance and illuminance accessories: Cosine receptor ・Other accessories: ND filter, standard diffuser plate

■Application

・Display brightness/color/contrast measurement ・White balance calibration for CRT displays/LCDs/plasma displays/projectors ・Evaluation of automotive/aircraft displays ・Calibration of video industry/digital cinema displays ・Measurement of reflectance/transmittance ・LED measurement and evaluation ・Color measurement in the medical/dental field

■Proven technology

The PR-788 is a spectral radiance meter developed based on the ultra-high sensitivity spectrometer PR-74X series used in research and development, quality control, quality assurance, and production sites.
