WHITE PAPER - Measuring Color Uniformity

WHITE PAPER - Measuring Color Uniformity

The color uniformity of light generated by LED luminaires plays a major role in many lighting applications. This makes it an important parameter to measure in both the R&D stage and during the quality assurance process. MKS Instruments has stayed abreast of this challenge by developing a new feature for its FluxGage photometrical system: the color uniformity measurement function. It allows quick evaluation of optical assemblies for color mixing and beam shaping. This whitepaper presents this novel feature of the system.

Horticultural Lighting - The Root to International Standards

Horticultural Lighting - The Root to International Standards

Plants have evolved to make the most of the conditions in which they naturally grow. For some plants, this environment will be fully supportive; it may be less so for others. In general, the plant with the fully supportive conditions will predominate in the absence of external intervention. Humans have changed plants over the centuries, selectively growing the plants that provide maximum perceived benefits in terms of color, smell, yield and, perhaps more recently, nutritional value. For most of our evolution, we have had to make use of the environmental conditions available. The desire for cheap food, all year around, and attempts to minimize "food miles" has increased the move towards providing totally constructed growing environments.
