CCD ARRAY SPECTROMETER CAS 120
A Poweful Spectrometer Designed Specifically For Production and Labortory Used
Instrument Systems CCD Array Spectrometer CAS 120 deploy the proven metrology from Instrument Systems even in price sensitive applications, such as LED production testing or quality assurance. CAS 120 spectrometer presents an appealing solution for cost-sensitive applications like LED production and quality assurance. Although costs have been reduced, technical innovations deliver even higher levels of reliability and robustness. The CAS 120 complies with the high requirements for measuring accuracy and versatile application without any compromises.
Unique technical innovations integrated in the CAS 120 result in a higher level of dependability and speed. These benefits are achieved alongside reduced cost even under the demanding conditions experienced in 24/7 production environments. The spectrometer also complies with the exacting requirements of accuracy and versatility without compromise.
A back-illuminated CCD area sensor with 2048 x 14 pixels is used for all models. Vertical binning enhances the dynamic range. Cost-intensive cooling of the CCD detector has been deliberately omitted for the CAS 120. Instead, the temperature of the CCD sensor is recorded each time a spectrum is measured, and the signal is then corrected.
