CAS 140D-HR High-resolution array spectroradiometer for laser and VCSEL
CAS 140D-HR – Ideal for precise measurement of laser diodes in the laboratory and production
The high-resolution CAS 140D-HR spectroradiometer is based on Instrument Systems successful CAS 140D series of array spectroradiometers. It was developed specially for the evaluation of narrow-band emission sources (laser, VCSEL) and offers extremely high spectral resolution with short measuring times.
The cooled CCD detector enables complex spectral measurements, also of extremely short light pulses, with low dark current and low noise. Since longer integration times are possible with the CAS 140D-HR, it is also suitable for very weak light sources.
Like all CAS models from Instrument Systems, the CAS 140D-HR also has a PTB traceable calibration. The HR series is available with USB or Ethernet interfaces. An integral density filter wheel and aperture for dark measurements enable fully automatic measurements while ensuring an extremely high dynamic range of the detector.
SpecWinPro software from Instrument Systems is available for comprehensive measurements in the lab. Additionally, CAS 140D-HR models are compatible with DLL and LabVIEW® drivers for integration in customized programs and production environments.
