(under subclass 237) Processes wherein the wave energy is either visible light or ultraviolet light.
(1) Note. Ultraviolet light is considered to have a wavelength of approximately 200 to 4000 Angstroms.
(2) Note. Visible light is considered to have wavelength of approximately 4000-7700 Angstroms.
(3) Note. Although a certain overlapping will occur at the lower wavelength of the ultraviolet spectrum and at the upper end of the visible spectrum, patents will be placed herein on the basis of the particular desired electromagnetic wave as noted in the specification.
(4) Note. Included in this subclass are treatments with any of the wavelengths within the visible spectrum.
