Round Particles Under the Microscope

Round Particles

This is part of a guide to the identification of particles seen in samples of free particles. This file includes round particles that are transparent, opaque, colored, black, colorless, homogeneous, heterogeneous, birefringent, isotropic, smooth, rough, conductive, non-conductive, reflective, absorbing, etc.

Transparent Round Particles

These are particles or round agglomerates that appear generally transparent or translucent with transmitted brightfield illumination.

Black Round Particles

These are particles or round agglomerates that appear generally opaque or very dark with transmitted brightfield illumination.
