Key Features and Capabilities

Precision Fixtures for Sample Loading

Simplify specimen mounting with dedicated fixtures that securely position removable sample tips during sample loading

Correlative focused ion beam (FIB) and atom probe tomography (APT) workflow

Directly mount compatible half-grid and single-point needle tips in FIB and CAMECA™ APT systems for efficient correlative characterization

Interchangeable Sample Tips for Diverse Specimen Geometries

Configure the holder for virtually any tomography specimen using removable, application-specific sample tips

How it works

The TEM Tomography Sample Holder integrates interchangeable removable sample tips into a flexible platform for high angle single-tilt electron tomography, conventional TEM/STEM imaging, and correlative atom probe tomography (APT). Samples are mounted onto the removable tip best suited to the specimen geometry before the tip is inserted into the holder for imaging and tomography experiments.

‍

A range of removable tip configurations supports 3 mm and 1 mm grids, FIB lift-out specimens, APT needle specimens, microfabricated chips, and custom sample geometries. Each tip is designed to maximize accessible tilt while minimizing sample shadowing, helping researchers obtain higher-quality three-dimensional tomographic reconstructions.

‍

While specifically engineered for automated tilt-series acquisition and tomographic reconstruction workflows, the holder is also widely used as a general-purpose single-tilt holder thanks to its exceptional stability, ease of use, and compatibility with a wide range of sample substrates. The removable tips allow the same specimen to be transferred between TEM tomography and atom probe tomograpy (APT) mounting systems, enabling direct correlative three-dimensional characterization.
