Fiber diameter and size distribution are key parameters to product performance. Fiber and pore dimensions need to be optimized for some applications. Filters, for example, require a target range of diameters for filtration efficiency. Surface porosity and fiber density also may need to be quantified. To obtain a useful and quantitative distribution of diameters or other parameters, many measurements have to be acquired. The high depth of field of the SEM allows for many fibers, including nanofibers, to be counted in a single image.

In less than a minute from load to image, the Phenom desktop SEM is the fastest way to get data and keep your research or product development work moving forward. Coupled with Automated Image Mapping and FiberMetric analysis software, you can quickly acquire quantitative information about fiber diameters and pore size.

The Z-axis scanning capability of the Zeta-20 optical profiler allows for many fibers that would normally be out of plane to be analyzed in one image, giving a better perspective than with a standard optical microscope. The Zeta-20 optical profiler quickly images and measures surfaces, including those with extreme differences in reflectance.
