Selected Application Ultra-low Drift The integration of the Photonic Probe Station into the attoDRY800 cryostat allows for characterization of photonic structures in a temperature range from 4 K up to 320 K. high-NA objective holder for lensed fiber probe holder for lensed fiber probe The stability of the light injection and detection is outstanding: ultra low drift of the transmitted signal intensity in the range of only a few percent in a period of several days is detected. A typical 4 h measurement is presented. The experiment schematics is shown below. attoMICROSCOPY Sophisticated Tools for Science Cryogenic Photonic Probe Station PAGE 155
