Lakeshore 1.5K Probe Station
Although the temperature of this probe station can be stabilized at <1.5K, employing the heater will yield stable operation up to 400K. The base temperature of this system is 1.47K +/- 10mK and typical base vacuum is in the 1E-7Torr range. Four probe arms, all DC or two DC and two 67GHz microwave, can be employed as well as a chuck bias connection. A fiber optic arm can be substituted for a DC probe arm and is able to be positioned in the chamber for 400-1700nm excitation. A high resolution microscope allows for active and accurate placing of probes at room temperature and at low temperature.
