New spectroradiometer speeds up LED production


Instrument Systems' new CAS 125 offers a unique 'Recipe' mode that enables time-optimised control

Product life cycles are getting shorter all the time. The corresponding increase in the number of product variants presents manufacturing companies with new challenges. P

To meet these needs. Instrument Systems has developed a new spectroradiometer CAS 125, focused on production-related applications for LEDs in the spectral range between 200 and 1100 nm. It will be presenting the device at Strategies in Light trade show, in San Diego from 11 to 13 February, 2020.

Instrument Systems has equipped 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 optimising long-term stability, according to the company.

The spectrograph design is based on the high-end CAS 140D device, which is already 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-optimised control of the spectrometer through parameterisation of successive measurements in Recipe mode on the CAS 125. This eliminates the time-consuming step of communicating with the PC to initialise each subsequent stage of the measurement process.

Another feature of the CAS 125 sensor is its built-in temperature stabilisation. This results in dark current behaviour 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 parameterise the flash trigger. This element helps users synchronise the spectrometer with other system components, for example by triggering a photodiode measurement.
