ABSTRACT:
An adjustable apodized lens aperture is described which is constructed using photochromic material. As the excitation energy increases, the aperture constricts so as reduce the amount of light through the aperture. As the excitation energy decreases, the aperture dilates so as increase the amount of light through the aperture.
