Abstract
Abstract An apparatus for producing spectrally different light distributions which have the same irradiance is disclosed. This apparatus contains a light source and an adjustable, opto-mechanical filter means. The filter means contains an adjustment means for simultaneously varying the spectral distribution of light passing through the filter while maintaining the flux of the light at a substantially constant irradiance level.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
121 words
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: 1. opto-mechanical means for simultaneously varying the flux and the spectral distribution of light which passes through said opto-mechanical means; and 2. opto-mechanical adjustment means for simultaneously varying said spectral distribution of said light which passes through said opto-mechanical means while maintaining said flux of said light which passes through said opto-mechanical device at a substantially constant irradiance level, wherein said opto-mechanical adjustment means does not comprise an electrical circuit.
Claim 2
Independent Claim
121 words
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: 1. opto-mechanical means for simultaneously varying the flux and the spectral distribution of light which passes through said opto-mechanical means; and 2. opto-mechanical adjustment means for simultaneously varying said spectral distribution of said light which passes through said opto-mechanical means while maintaining said flux of said light which passes through said opto-mechanical device at a substantially constant irradiance level, wherein said opto-mechanical adjustment means does not comprise an electrical circuit.
