Instrument Systems GmbH
Instrument Systems will be presenting its latest VTC 4000 infrared camera for the near-field analysis of narrow-band emitters. Industry-standard VCSELs emit in more than one polarization state, 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...See full product
