Model 2030 – Ultra-Narrow Gap Tomography Holder

Key Features

Key Features of the Fischione Model 2030 Ultra-Narrow Gap Tomography Holder include:

  • Room temperature tomography in ultra-high resolution microscopes
  • Extended field of view at high-tilt angles
  • Tilt angles up to 90°
  • Suitable for ultra-narrow gap (< 3 mm) pole-piece geometries
  • Optimised specimen protection during insertion into the TEM

Tilts Up To 90° in Pole-Piece Gaps Less than 3MM

Factors such as of specimen thickness, size, specimen support, pole-piece geometry, aperture, and specimen holder configuration influence the ability to be able to collect three dimensional information over a range of tilt angles using room temperature TEM.

Ideally, the pole-piece gap should be large and unrestricted to obtain high-tilt angles in TEM. In reality, some ultra-high resolution materials science TEMs, this gap can be less than 3mm, making high tilt measurement impossible. The Ultra-Narrow Gap Tomography holder permits tilting up to 90° while providing a maximised field of view.

Advanced Clamping And Retracting Mechanisms

The Ultra-Narrow Gap Tomography Holder caters for a 1.5 mm square or round TEM specimen or grid into a cartridge, securing it with a single clamp.

To protect the specimen during holder insertion into and removal from the TEM goniometer, the Ultra-Narrow Gap Tomography Holder features an advanced mechanism that retracts the specimen cartridge into the body of the specimen holder.
