WP690E-Circ Imaging Circadiometer – Light Evaluations for Human Vision Science

WP690E-Circ alllows users to acquire precise scotopic, ipRGC, S-cone, L-cone and M-cone, radiance measurements of displays, luminaires, or other visual scenes. Photometrica software provides the tools to analyze single or many measurement images to gain understanding of the impacts to human physiological responses.

The WP690ES-Circ includes a built-in spectroradiometer for the acquisition of scene spectra. Measurements include angular radiance and radiant intensity distributions, and the ability to acquire high dynamic range scenes where intense lighting is combined with dark areas.
