The UHV 300 and 350 subsystem packages take advantage of the inherent stability of the “Beetle” design. The vacuum chamber is designed with multiple ports targeted at the tip/sample interface. In addition to excellent operator view of the sample and internal operation, the system provides full optical access for research techniques which require line of sight access to the sample/tip interface such as apertureless NSOM. Furthermore, the sample stage is fixed (vibration isolation is external) and the microscope is free of any magnetic field sources providing an ideal research platform for techniques requiring a fixed focal point as in combined SPM/optical experiments, where magnetic field interference is critical or external magnetic fields will be applied. |

| The UHV 700 and 750 subsystem packages combine the stability of the “Beetle” with an internal spring suspension and eddy current dampening system for applications where external air legs are not a practical option. The UHV 700 series system is also designed to provide the user with excellent optical access to the sample and the spring suspension system can be easily locked for sample and tip exchange or non-SPM applications where a fixed sample focal point is required. |
