3. The 3D Profiler

one of the most interesting and useful feature of the metallurgical microscopes is having a 3D profiler which allows measurement of the height and/or thickness of a sample. This is a great tool for inspection of the materials or scaffold are made in three-dimensional, such as 3D tissue or dental cements. BIOIMAGER has recently added an output format of .stp to the constructed 3D microscopy images then you can easily print out what you observe under microscope.

 Analysis Example: Fiber Separation Analysis

The application is designed to separate and measure crossing fibers on images. The fibers on the images can be straight or bent. It can be used to measure distribution of thin inclusions or asbestos fibers.

Researchers have been looking for an easier way to measure the lengths and widths of overlapping fibers. Most researchers end up manually measuring fibers – a process that is not only time consuming, but can introduce inconsistencies. Now, with the Image-Pro Premier Fiber Separation App, it is possible to measure and classify the length and thickness of overlapping fibers with one click.

This App is designed for applications where the entire fiber is visible in the image.
