Typical applications:

Time-of-flight use of VCSEL arrays
If laser diodes and VCSEL arrays are to be used for time-of-flight applications, their characterization must be spectral and performance-related, and additionally in terms of emissions and the generated pulses. For this purpose, Instrument Systems offers absolutely calibrated, high-speed spectroradiometers such as the CAS 125 with diverse accessories. Widely used in the production environment is a system that couples the emitter into an integrating sphere and measures it instantaneously with the aid of photodiodes and a spectrometer of the CAS series. Thanks to a fast photodiode and the emitter’s specially developed control electronics, this VCSEL measurement solution from Instrument Systems guarantees the characterization of pulses in the single-digit nanosecond range and capture of the LIV curve.
