Description:
The CAS 120 is ideal for all measurement applications of LEDs, OLEDs and solid-state lighting products. Firstly, the comprehensive range of accessories transforms the setup of the spectrometer into a universal lab workstation. Secondly, the robust design, the short measuring times and attractive pricing make the CAS 120 ideal for use in cost sensitive production environments. The wafer with processed LED chips provides the opportunity to determine the properties of the future LED for the first time. In particular, this is crucially important when manufacturing white LEDs where tight production tolerances and a high yield for the final white LEDs can only be guaranteed by precise testing for the optical and electrical parameters of the blue LED chips used.

In addition, these probes can be operated under a microscope and permit fast configuration of the wafer and continuous positional control during testing. The probe’s high light throughput also facilitates very short measuring times even with low power LED chips. Moreover, the CAS 120 is equipped with a reliable, screw-fit USB interface and a separate TTL trigger I/O interface. The hardware trigger is necessary to enable precise timing and synchronization with other instruments like current sources. Minimizing synchronization errors and delays is especially critical for wafer probing and LED sorting. Trigger cables are available for direct connection of standard current sources to the CAS 120.
