Optical measurement equipment Spectroradiometer Wide dynamic range spectroradiometer PR-788
Asahiko Trading Co., Ltd.
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
