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.
Claims14
A apparatus for continuously producing at least two spectrally different light distributions possessing substantially the same irradiance, wherein said apparatus is comprised of a light source for providing light and a adjustable, opto-mechanical filter means for attenuating light from said light source, wherein said adjustable, opto-mechanical filter means is comprised of:
- (a) a substantially circular composite filter comprised of a substrate with a top surface and a bottom surface and, contiguous with at least one of said top surface and said bottom surface a first coating of color conversion filter material and a second coating of neutral density filter material;
- and
- (b) means for rotating said circular composite filter.
A apparatus for continuously producing at least two spectrally different light distributions possessing substantially the same irradiance, wherein said apparatus is comprised of a light source for providing light and a adjustable, opto-mechanical filter means for attenuating light from said light source, wherein said adjustable, opto-mechanical filter means is comprised of:
- (a) a first composite filter disposed beneath said light source, wherein:
- 1. said first composite filter is comprised of a substrate with a top surface and a bottom surface and, contiguous with at least one of said top surface and said bottom surface, a coating of neutral density filter material;
- (b) a second composite filter comprised of a color conversion filter and a neutral density filter, wherein said second composite filter is disposed below said first composite filter;
- (c) first means for moving said first composite filter;
- and
- (d) second means for moving said second composite filter.
