OmniProbe 350 is a 3-axis, port mounted manipulator featuring piezoelectric motors with closed loop feedback, ideally suited for routine TEM lamella preparation. Precise and intuitive control means you can work quickly and confidently without the risk of damage or sample loss.
Based on our 9th generation probe design OmniProbe 350 delivers precise nanoscale control from a compact, port mounted footprint which minimises interference with other detectors and accessories. With a stable probe platform and sub-nanometre piezoelectric motors, our current generation of probes has low vibration, low drift, and superb positioning accuracy, which is combined with our intuitive user interface, where movement direction is calibrated to the image.
The result is class leading performance for routine lift-out and when combined with a variable tilt grid holder OmniProbe 350 can create plan-view and TKD samples without direct handling of the grid or complex multistage lift-out.
Discover why OmniProbe 350 is the best-in-class 3-axis nanomanipulator for fast and efficient routine TEM Lamella preparation
Superior linearity - Linearity is a measure of the deviation of the probe tip from the requested movement direction. A probe that moves in a straight line in all directions can:
Intuitive user interface where controls directly reflect the movement of the probe in the electron image
Smooth continuous motion - Lamella preparation workflows require the probe to make physical contact and smooth motion ensures this can be done without risk of dropping or damaging the sample.
Precise movement with stored positions
Stable probe platform - Stability is a combination of vibration and drift. Attaching samples to the probe tip is done by a gas deposition process that can take several minutes. Any drift or vibration of the tip during this process can result in stresses within the sample or sudden movement of the sample at the point it is cut free
Port mounted design retracts fully within the chamber when not in use so there is no compromise to your microscope
Probe electrical connection includes +/-10V power supply for voltage contrast imaging
