Abstract

The calibration units of today's instruments are often limited by the fact that a reference source can feed one or even two outputs without having much loss. As a result, there is often a trade-off between throughput and system size to be made. We have designed a novel Light Distribution System based on pneumatic actuators that allows a defined number of sources to be selected and several outputs to be fed at the same time.
