Abstract
An apparatus for generating a spectral distribution. This apparatus contains a light source and a single filter. The single filter is comprised of a color correcting filter material and a neutral density filter material. When the apparatus is adjusted, the spectral distribution of the light which passes through it varies continuously, but the brightness and/or irradiance of such light is substantially constant.
