Proven optical design combines with innovative technology
As in the industry leading CAS 140CT from Instrument Systems, a Crossed Czerny Turner Spectrograph with back-illuminated CCD detector forms the core of the spectrometer. This means that the CAS 120 guarantees exceptionally low straylight and a very high level of optical precision. Cost-intensive cooling of the CCD detector with 2048 x 14 pixels was deliberately omitted for the CAS 120. Instead, the temperature of the CCD detector is recorded each time a spectrum is measured, and an innovative algorithm automatically corrects the signal.
The newly developed filter wheel with density filters OD 1 to OD 4 comes without any mechanical position switches and always guarantees exact filter positions. It expands the total dynamic range of the CAS 120 to 8 decades, enabling the measurement of low and high light intensities without manual intervention in the test procedure. The CAS 120 is equipped with a USB interface and a TTL trigger I/O. The hardware trigger permits synchronization with other instruments which is essential for exact measurement results during fast production testing.
Versatile software support
Instrument Systems supplies a DLL and a LabVIEW® driver for use in production environments and at automated measurement stations. SpecWin Pro and SpecWin Light spectral software packages have been developed for a wide range of laboratory applications with functions for analysis and documentation of test results.
