Film. A rainbow of colors indicates the thickness
of a clear, organic film used to mount microscopic particles.
The deep blue and brown on the left of this optical micrograph
show that the film is less than a micrometer thick, the right
thickness for embedding single particles for microstructural
analysis. In an AML ultraclean room, NIST chemists mount and
analyze individual particles for forensic, advanced materials,
and other researchers. |
