Description
SR-5 is a new-generation spectroradiometer that measures from low luminance to high luminance with high sensitivity and high speed.Selectable 0.1°, 0.2°, 1°, and 2° measurement angles provide a luminance measurement range from 0.001 cd/m² to 500,000 cd/m²,
meeting the requirements of a wide range of display and lighting applications.
SR-5 realizes reduced measurement time through renewal of the optical system and improvement of the internal processing algorithm.
Significant improvement in usability is achieved by adopting a large-size color touch panel.
Principal use
￭ Comprehensive evaluation of optical characteristics, including luminance, chromaticity, color temperature, contrast,
and luminous intensity distribution of displays and lighting products.
￭ High-precision measurement of luminance and chromaticity on small surfaces, such as automotive instrument panels,
audio systems, and operation/control panels.
￭ Evaluation of the luminous performance of traffic signs, traffic signals, and various special light sources.
