Ultra-Narrow Gap Tomography Holder
  • Room temperature tomography in ultra-high resolution microscopes
  • Extended field of view at high-tilt angles
  • Can tilt up to 90º
  • Suitable for ultra-narrow gap (< 3 mm) pole-piece geometries
  • Optimized specimen protection during insertion into the TEM

Tilts up to 90° in pole-piece gaps less than 3 mm

The ability to collect three-dimensional information over large ranges of tilt in room temperature transmission electron microscopy reaches a mechanical limitation dictated by the combination of specimen thickness, size, specimen support, pole-piece geometry, aperture, and specimen holder configuration.

To obtain high-tilt angles in transmission electron microscopes, the pole-piece gap should be large and unrestricted. However, for some ultra-high resolution materials science microscopes, this gap can be less than 3 mm. Hence, high tilt with traditional 3 mm specimen geometry is not possible. The Ultra-Narrow Gap Tomography Holder is capable of tilting up to 90º while providing a maximized field of view.

Advanced clamping and retracting mechanisms

The Ultra-Narrow Gap Tomography Holder accepts 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.
