Helios Series
Helios Imaging Colorimeter


Versatile highest accuracy 2D imaging colorimeter

Helios XYZ 12 MP Imaging Colorimeter Specification

The Helios is the ultimate 2D imaging colorimeter. The CMOS sensor is combined with high accuracy interference XYZ filters. Additional OD filters with virtually flat response assure a high dynamic range. In order to mitigate the angle effects of interference filters the lens system is image space telecentric. This in combination with the in-house produced extreme uniform and accurate filters makes the Helios stand apart from any other solution on the market when accuracy is key.

“Perfect match to the 2° CIE 1931 colormatching funcions—from X to Z.”

Tailored to meet the highest accuray demands

Fresnel would love Helios

A custom image space telecentric lens assures that the natural angle dependence of interference filters is taken care of by assuring perpendicular light transmission in the filter plane.
