include the ranges “100-200 nm” and “300-200 nm,” with one reference characterizing such
spectral ranges as “near-ultraviolet (uv) 200-400 nm,” and it is apparent that “classifications may
differ due to the phenomena of interest.” 5
upon any further consideration thereof before the examiner subsequent to this appeal.

regions of electromagnetic spectrum (1) (illuminating engineering). For
convenience of reference, the electromagnetic spectrum is arbitrarily divided as
follows:
Vacuum ultraviolet
Extreme ultraviolet 10-100 nm
Far ultraviolet 100-200 nm
Middle ultraviolet 200-300 nm
Near ultraviolet 300-800
Visible 380-770 nm
. . .
Note: The spectral limits indicated above have been chosen as a matter of practical
convenience. There is a gradual transition from region to region without sharp
delineation. Also, the division of the spectrum is not unique. In various fields of
science, the classifications may differ due to the phenomena of interest. Another
division of the ultraviolet spectrum often used by photobiologists is given by the
International Commission on Illumination (CIE):
UV-A 315 to 400 nm
UV-B 280 to 315 nm
UV-C 100 to 280 nm

Ultraviolet radiation
Electromagnetic radiation in the wavelength range 4-400 nanometers. The ultraviolet
region begins at the short wavelength (violet) limit of visibility and extends to the
wavelength of long x-rays. It is loosely divided into the near (400-300 nm), far (300-
200 nm), and extreme (below 200 nm) ultraviolet regions . . . In the extreme
ultraviolet, strong absorption of the radiation by air requires the use of evacuated
apparatus; hence this region is called the vacuum ultraviolet. . . .
Biological effects of ultraviolet radiation include . . . germicidal action [in the far or
300-200 nm ultraviolet region]. . . .
