Advanced LED Color Matching Technology
The DLS moduLight 2-1700 combines multiple colored LED sources to generate a highly balanced and complete light spectrum that exceeds the minimum requirements of ISO 3664:2009 and ISO 3668. This advanced LED technology delivers reliable spectral performance without the maintenance requirements associated with traditional fluorescent lamps.
The integrated Fresnel-type prismatic lens system creates extremely homogeneous illumination across the entire viewing area while minimizing glare and reflections. This allows professionals to evaluate large-format samples with greater accuracy and consistency.
Illuminant Characteristics
The JUST Normlicht DLS moduLight 2-1700 features controlled asymmetrical illumination designed for viewing from one fixed position. This ensures repeatable viewing conditions while reducing unwanted reflections during color evaluation.
