CAS 140CT-HR – High Resolution Array Spectroradiometer (Discontinued)
View our latest version of this instrument, the CAS-140D
The high-resolution CAS 140CT-HR is based on Instrument Systems’ high-end array spectrometer CAS 140CT, a product line that has achieved extraordinary success around the world. The CAS 140CT-HR is particularly designed for the measurement of narrow band emitters, e.g. laser diodes. Therefore, the spectroradiometers combine the demands of high spectral resolution and short testing times for sophisticated measurement tasks in production and laboratory environments.
All CAS 140CT-HR models are offered with a PTB traceable calibration. They are factory-equipped with a USB interface and optionally available with PCIe interface for extended triggering possibility. The integrated density filter wheel and the dark shutter additionally facilitate fully automated measurements over an extremely broad detector signal range. The spectroradiometers can be operated with Instrument Systems’ SpecWin Pro software for advanced laboratory applications. In addition, they are compatible with DLL and LabVIEW drivers for creating proprietary programs and integration into production equipment.
