  • What is Micro Contamination?

     Materials have foreign substances on their susrface composed or organic and/or inorganic's particles or films.  Sometimes the physical and chemical properies of materials are defined by the surface compositon of the bulk materials.

     In the case of optics the absorption profile can change significantly depending on the presence or absence of a susrface film.

     Electronic components lifetimes can be effected by surface contamination i.e. residue from flux or particles.  This can lead to issues with heat transfer etc...

     The wear rate of materials can be affected by its surface composition.

     The ultimate pressure of any vacuum system is dependent on surface composition and cleanliness.
