High-performance for wavelengths in infrared

At LASER WoP 2022 Instrument Systems will be presenting its latest spectroradiometer CAS 140D IR for measurements in the SWIR (short-wave infrared) wavelength range. The latter offers the proven high measurement accuracy and reliability of the CAS140D series - internationally recognized as a reference - for wavelengths of 780–1700 nm. Compared to its predecessor, the CAS 140D IR has a significantly better performance in signal sensitivity, stray light suppression and electronics. Visit us at booth A6.221.

Polarization-controlled VCSEL testing

At LASER WoP 2022 Instrument Systems will be presenting its latest VTC 4000 infrared camera for the near-field analysis of narrow-band emitters, e.g. VCSELs or lasers. Industry-standard VCSELs emit in more than one polarization state, each with different polarization angles, thus impeding error-free measurement. Thanks to a new one-shot process, the VTC 4000 simultaneously measures the spatial polarization of single emitters of an array and supplies the necessary information to reduce the polarization dependency of the measurement setup. This procedure minimizes the error budget of the VCSEL test system and provides highly accurate measured values for the eye safety of the laser source. This enables manufacturers to exploit the full power efficiency of VCSELs/lasers while guaranteeing safe operation. Come and visit us at Booth A6.221.
