Atlas

Model : Atlas

Description :

The Atlas system is the ultimate imaging colorimeter with an integrated NIST-traceable calibrated spectrophotometer (380-780nm) and a fast sampling light meter, combining three fundamentally different devices into one solution giving it unprecedented capabilities and flexibility. Main applications are display testing (including LED panel) and Luminous Surface testing.

Highlights
