Open Cell Foam Fragment

The example of foam fragments here were on a tapelift from an Office. These particles are often misidentified as glass fiber fragments. When viewed at higher magnification they are easier to correctly identify. This is an enlarged image of the fragment viewed with a 10X, NA 0.25 objective. The trilobate cross-section of the particle is a little clearer. The bright particles in this image are paper fibers and the film to the right of center is a skin flake
