Scanning Probe Microscope Solver HV
Solver HV is intended for work in high vacuum conditions and controllable gas medium. Measuring head Smena HV is designed by vacuum technology using vacuum compatible materials. The case of the head is without covering. Its wires have no braid and sockets are metallized. To decrease the thermal drift, Smena HV is supplied with a preamplifier with reduced thermal emission and the temperature compensators are installed. Smena HV is supplied with the special motorized approach leg to provide approaching of the probe to the researched sample. It is based of the stepper motor intended for work in conditions of high vacuum. Smena HV head is set to the vacuum chamber on the stage. The stage is supplied with special handles for more comfortable setting and taking out the head with the stage from the vacuum chamber. It is possible to work with measuring head Smena HV in room conditions, as with usual Smena head. For this purpose the scanning unit of Smena HV is connected with SPM Controller directly passing the vacuum chamber using the enclosed extension cord.
