New spectroradiometer speeds up LED production

For the CAS 125 spectroradiometer, Instrument Systems decided to equip the device with a CMOS sensor that is linked to a specially developed electronic readout circuit. This combination enables very low measurement times of 0.01 milliseconds while simultaneously optimizing long-term stability. The spectrograph design is based on the high-end CAS 140D device, which is already well established in the market. This gives the CAS 125 a level of optical performance comparable to that of the CAS 140D in terms of both stray light suppression and optical throughput. The device-specific electronic readout circuit enables time-optimized control of the spectrometer through parameterization of successive measurements in Recipe mode on the CAS 125. This eliminates the time-consuming step of communicating with the PC to initialize each subsequent stage of the measurement process.

Another unique feature of the CAS 125 sensor is its built-in temperature stabilization feature. This results in dark current behavior that is independent of the ambient conditions, enabling the CAS 125 to ensure optimum long-term stability even in environments where temperatures fluctuate. A further highlight is the ability to parameterize the flash trigger. This element helps users synchronize the spectrometer with other system components, for example by triggering a photodiode measurement.

These key features – temperature stabilization and Recipe mode – are two of the CAS 125’s unique selling points. They significantly improve automated processes in LED production, thus boosting productivity.
