Multispectral Lighting Systems

Standard Multispectral Lighting System

The Multispectral Lighting System (MLS) is designed to illuminate test charts of up to a width of 2 meters with more than 90% uniformity for image analysis. This new lighting system uses 16 LED channels that can be fully controlled independently and can automatically fit a spectrum with a closed loop. (Some standard spectra are pre-calibrated.) The LED channels are DC-driven, ensuring flicker-free light, although LED flicker can be activated. This lighting system can reach very low light (down to 0.1 lux with 10% precision).

An illuminance feedback loop automatically stabilizes light levels, and the entire system is computer-controlled so that you can program your own lighting scenarios, including the color temperature. The software ensures perfect repeatability of your illumination conditions.​

Sunlight-Near Infrared Multispectral Lighting System

This lighting system has the same characteristics as the standard MLS product, but comes with 4 additional LED channels in near-infrared (NIR) and one additional LED channel in visible light. This creates an unprecedented ability to mimic daylight by reaching light levels up to 50K lux with a spectrum that goes through the full range of visible light and NIR.​
