Tilts up to 90º in pole piece gaps less than 3mm
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 3mm. Hence, high tilt with traditional 3mm specimen geometry is not possible. The Model 2030 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 Model 2030 accepts a 1.5mm 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 Model 2030 features an advanced mechanism that retracts the specimen cartridge into the body of the specimen holder.
