Fast Production Test of UV-LEDs

IS UV LED Test17 December 2018 – Within its well-established CAS-series of spectroradiometers, Instrument Systems has developed a novel series-type CAS 140D-157. This new system measures precisely and reliably not only within the visible spectrum, but also in the UV. Coupled with a PTFE-coated integrating sphere, the system permits for fast 24/7 production tests of UV emitters to be run.

With the new CAS 140D-157, Instrument Systems presents a very flexible array spectroradiometer that measures precisely and reliably in the visible as well as in the UV spectral range between 200 and 830 nm. The spectroradiometer is based on the CAS 140D, which is internationally accepted as standard in light measurement. The CAS 140D possesses excellent measurement accuracy due to a very effective suppression of stray light. Additionally, stray light effects can be improved even further by an optional stray light correction. Moreover, the novel UV-model is equipped with a customized diffraction grating, which assures twice the optical throughput at 200 nm in comparison to the previous model.

In combination with spectroradiometers, integrating spheres serve as coupling optics for optical emitter. At Instrument Systems, the ISP 50-UV with an inner diameter of 50 mm has been developed especially for this application in the UV. The interior is coated with the highly reflective material PTFE (Polytetrafluoroethylen). In contrast to the commonly used Barium sulphate coating, PTFE generates a higher optical throughput in the UV within the integrating sphere.

The combined measurement system of CAS 140D-157 and ISP 50-UV allows for simultaneously precise and fast measurements in the UV spectrum. UV radiant flux as well as further spectral parameters of UV-LEDs can be determined within a 24/7 production control or during laboratory applications. All UV measurement systems provided by Instrument Systems come with traceable calibration according to PTB.
