Components Micro-optics for LED light sources

Modern LEDs form the basis for highly efficient light sources for a vast number of applications, such as general illumination, image ­projection, measurement, microscopy, etc. In addition to the emitter, the light source comprises both a primary and a secondary optics system, responsible for gathering the light emission close to the chip facet and for beam shaping and thus also for intensity distribution in the image plane, respectively. Secondary optics with tandem arrays enable the realisation of miniaturized light sources for homogeneous illumination of circular or rectangular areas, or even of line foci, all with high brightness.
