High speed reliability

Asteria Specification

Asteria is a high speed photometer suited to measure illuminance. Swift and steady as it is, Asteria is able to measure waveforms of light source to determine flicker characteristics. Designed for in-line use, Asteria is available in multiple configurations and can come with an M8 fiber connector for set ups where space is limited.

“Swift and steady sampling for waveforms and flicker characteristics.”
