Description
Admesy’s Asteria is a high-speed measurement device suited for luminance, illuminance and flicker measurements. Based on the popular Admesy platform the Asteria is designed for in-line use with integrated calculating power for easy implementation and high speed measurement results in production settings. The Asteria is available in multiple configurations: the lens based system is capable of measuring luminance [cd/m²] and flicker, its cosine corrector configuration allows illuminance [lux], luminous intensity [cd] and flicker measurements. Fibre versions are also available to connect to remote cosine correctors, lens systems or connect to integrating spheres.
