VTC 4000 – Fast testing of VCSEL arrays in the near-field range with the highest degree of accuracy The VTC 4000 near-field camera from Instrument Systems was specially developed for the ultrafast, precise 2D analysis of VCSEL arrays. It enables polarization-controlled characterization of all relevant parameters simultaneously for the single emitters of the array. Thanks to a unique calibration concept, 2D quality analysis is performed with unprecedented measurement accuracy. Like all measuring instruments from Instrument Systems, the VTC 4000 camera is traceably calibrated to national standards (PTB) and delivers measurements with absolute precision. The innovative calibration concept of the VTC 4000 is based on flat-field and polarization correction. Polarization correction takes place in the form of an in-line analysis of the emitted light and corrects the polarization dependence of the optical system. This calibration enables absolute measurement of the power and polarization properties of each single emitter within the camera’s field of vision in a one-shot process.
