CAS 125 Spectroradiometer

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 initializing of each subsequent stage of the measurement process.
