<p>An apparatus (10) for producing spectrally different light distributions which have the same irradiance is disclosed. This apparatus contains a light source (28) and an adjustable, opto-mechanical filter means (128, 130). The filter means (128, 130) contains an adjustment means (22) for simultaneously varying the spectral distribution of light passing through the filter (128, 130) while maintaining the flux of the light at a substantially constant irradiance level.</p> |
