OPTICAL ELEMENT HAVING AN APODIZED APERTURE |
摘要 |
Provided is an optical element with an electrochromic apodized aperture having variable light transmittance in response to the amplitude of an applied voltage. The apodized aperture includes (i) a first substrate having a planar inner surface and an outer surface, (ii) a second substrate having an outer surface and a non-planar inner surface opposing and spaced from the planar inner surface of the first substrate, wherein each of the planar inner surface of the first substrate and the non-planar inner surface of the second substrate has an at least partial layer of transparent conductive material thereover; and (iii) an electrochromic medium disposed between the planar inner surface of the first substrate and the non-planar inner surface of the second substrate.
