Spectral, spatial and temporal optimization of solid-state light engine output

This article is brought to you by: 

Specifications for illumination systems for biomedical imaging and industrial metrology generally converge on spectral, spatial and temporal light output characteristics. This article describes some of the ways in which solid-state light engines consisting of arrays of solid-state light sources, a mix of LEDs, light pipes and lasers, allow for the customisation of specifications to meet application-specific lighting requirements.
