Precise, in situ planar rotation
The Fischione Model 2040 Dual-Axis Tomography Holder is for transmission electron microscopy imaging or analysis that requires in situ specimen rotation. Acquiring a dual-axis tilt series enhances the information contained in the tomogram.
The Fischione Model 2040 Dual-Axis Tomography Holder features an optimal tilt angle range in narrow gap (~5 mm) pole-piece geometries, while maintaining microscope resolution.
A fully jeweled mechanism provides ultra-precise, in-plane specimen rotation, while maintaining eucentricity.
The FlexiClamp is a spring-type, annular ring which securely clamps the specimen into the specimen cup. It maximizes specimen visibility, even at high-tilt angles. A dedicated tool facilitates the use of the FlexiClamp.
Initially, the specimen can be fully rotated through 360º to orient either the grid bars or a specimen feature to the alpha tilt axis. Once the specimen is properly oriented, the first tilt series is acquired. A two-position precision indexing mechanism provides 90º in-plane rotation. These features greatly facilitate the acquisition of a dual-axis tilt series.
