Wood, Textile & Paper

High resolution and large depth of focus are capabilities that make TESCAN SEM an ideal instrument to observe the topography of non-conductive materials such as wood, textiles and paper.
For the purposes of studying these materials, TESCAN FEG-SEMs provide the highest resolution imaging even at low accelerating voltages. The variable pressure mode UniVac and the LVSTD detector are especially aimed for samples that cannot be prepared by using standard methods or coated with metals.
  • Textiles can be produced from a wide range of materials. These materials include those of animal origin (such as wool and silk), materials extracted from plants or shrubs (such as cotton, flax or jute), materials of mineral origin (such as glass, fibres and asbestos), and synthetic materials (such as polyester or nylon).
  • Textiles can be made with different properties depending on the type and thickness of the particular fibre.
  • Paper is a material which is made by pressing fibres such as cellulose pulp. It is used throughout our life in packaging, construction processes, etc.
  • Wood is an organic material that is used in the construction and furniture industry for building structures. Other wood products include glued laminated timber, wooden structural panels, plywood, oriented strand boards and composite panels.

3D focused ion beam tomography of wood sample
While X-ray tomography achieves a voxel size of approximately 150 nm focused ion beam (FIB) tomography can go even below 10 nm. In FIB tomography, the voxel size is basically limited by the maximum resolution of the SEM which is used for imaging. In general, the process works on the ground of sequential imaging of many surfaces (stacks) polished by FIB. The stacks are then used to reconstruct a 3D model of the specimen. The 3D model can be generated with thousands of slices, at a rate of one slide per minute.
