DLS multiLight

Specifications

The optimized control system enables much easier LED-based assessment. In addition to the illuminants D50, D65 and UV-A, two specific illuminants can be added to the DLS multiLight, according to customer's needs. Furthermore, the UV content can be turned ON/OFF and stored proofing settings can be easely switched on or off at the touch of a button.
