CONTINUOUS ROTATION TOMOGRAPHY HOLDER

Conventional tomography holders use the microscope's goniometer for rotation. This approach results in a tilt series with missing wedge since typically TEM goniometers have a limit for alpha tilt, typically around 70 degrees. ZoNexus has designed a tomography holder with a built-in motor that allows 360 degrees rotation. This approach not only allows to obtain much higher resolution tomograms but also allows fast acquisition, especially when used along with direct electron detector

SALIENT FEATURES

• 360 degree rotation

• Tomography holder can be rotated continuously. Alternatively, the holder can be rotated to a set angle and data can be collected using the goniometer and the microscope's tilt series acquisition software.

• Continuous rotation via high precision piezo-motor

• Detatchable tips, allowing transfer of samples prepared using FIB. Three types of tips are included: needle, half grid (for FIB samples) and 3.05 mm grid

• Custom configurations for the tip design and materials available.
