Precise, in situ planar rotation

The Model 2045 Motorized Dual-Axis Tomography Holder is based on the revolutionary Model 2040 Dual-Axis Tomography Holder. The Model 2045 is designed for room-temperature applications when TEM tomographic imaging or analysis requires software-controlled, automated, in-plane rotation of the specimen. The specimen drive is motorized and interfaces with the microscope’s control system, which allows full software integration of both specimen tilt and rotation.

The Dual-Axis Tomography Holder features an optimal tilt-angle range in narrow gap (~5 mm) pole piece geometries. A fully jeweled mechanism provides ultra-precise, in-plane, specimen rotation while maintaining eucentric height.

The specimen can be automatically rotated from +180° to -180° to initially orient either the grid bars or a specimen feature to the alpha-tilt axis. After the acquisition of the first tilt series, the specimen can then be rotated 90° with respect to the first orientation for the subsequent acquisition of the second tilt series.

Acquiring a dual-axis tilt series enhances the quality of information contained in the tomogram. Motorization is essential when conducting conical tilt tomography, as well as any other high-throughput application.

Automation through the microscope facilitates dual-axis tomography via remote operation, which is especially useful for TEMs that are located in an enclosed environment.

The holder features a FlexiClamp, a spring-type, annular ring that securely clamps the specimen into the specimen cup. It maximizes specimen visibility, even at high-tilt angles.
