Fields of application

End-of-line testing in LED production
Thanks to its robustness and short measuring times, CAS 140D array spectroradiometers from Instrument Systems are ideally suited to 24/7 production. With back-illuminated CCD sensors cooled to -10 °C it fulfils the most demanding requirements in terms of sensitivity and stability, e.g. in LED production control. Due to its improved optical and mechanical design the CAS 140D is smaller, more functional and even easier to integrate into existing production lines. It has a particularly short integration time and a throughput-optimized spectrograph with minimum levels of stray light. With a wide selection of accessories, the array spectrometer has become a complete system for all spectroradiometric and photometric measurement tasks.

Display production testing
As a 3-in-1 system the LumiTop 2700 combines a RGB camera and flicker diode with a high-end spectroradiometer of the CAS series. It is used for the fast but at the same time highly accurate characterization of displays in production. Due to the constant reference check with the CAS 140D, its extremely high measurement accuracy applies across the entire field of view of the camera. The LumiTop 2700 enables various test applications to be conducted at a single test station. Thanks to the accompanying LumiSuite software with software development kit, the system can be easily integrated into production lines or used in the laboratory for a broad range of evaluation options.
