Abstract:

This patent covers a method for producing durable optical baffling materials comprising polishing to a mirror finish the surface of a starting material, preferably having a very fine-grained structure, and then bombarding the surface of the starting material with low energy 0 to 50 keV pulsed electrodes at a pulse length of about 0.1 microseconds. A fluence of 0.5 calsq cm renders the surface completely black in appearance, retaining none of its initial mirror-like properties. Author
