DISCUS
From ColorWiki
basICColor DISCUS was a high-end colorimeter and universal instrument for the accurate measurement of color monitors, projectors, large screen systems, standard lighting fixtures and ambient lighting.
DISCUS was suitable as a measuring device for soft proofing in pre-press, for color-critical applications in photography, design, digital signage and video production.
The DISCUS was no longer in production after the basICColor company was reformed in 2019.
