The light quality of LEDs, light detectors (photodiode and phototransistor) and photometric assemblies has an enormous importance for the success of a product. Due to the complete parameterizable and automated measuring stations at HTV measurement or selection of optical and electrical parameters can be carried out in production quantities. In the HTV-analytics laboratory photometric assemblies can also be inspected in view of their quality and functionality.
