Model 2020 Advanced Tomography Holder
- Ideal for room temperature electron tomography
- High tilt in narrow gap pole pieces
- Optimized specimen retention
- Extended field of view
- Easy, accurate specimen positioning
The Model 2020 Advanced Tomography Holder is a revolutionary room temperature specimen holder for transmission electron microscopy (TEM) featuring high tilt and extended field of view. It allows data collection over wide tilt and translation ranges, even in restrictive pole piece gap geometries.
Advances in microstructural characterization require the ability to analyze structure and chemistry in three dimensions. However, most TEM techniques are limited to producing two-dimensional information. Tomography on the other hand, combines two-dimensional data sets taken at various tilt angles to produce a three-dimensional reconstruction. The Model 2020 is ideal for electron tomography in the life and physical sciences as well as any other application requiring high specimen tilt.
A streamlined specimen clamping mechanism eliminates the shadowing associated with most holders at high tilt angles. The clamping mechanism accepts a standard 3mm diameter TEM specimen and accommodates a wide range of specimen thicknesses. Specimens are secured with two diametrically opposed clamps that produce an evenly distributed force on the specimen.
