Optical element having an apodized aperture
First Claim
1. An optical element comprising an electrochromic apodized aperture having variable light transmittance in response to the magnitude of an applied electrical voltage, the apodized aperture comprising:
- (i) a first substrate having a planar inner surface and an outer surface, wherein the planar inner surface has an at least partial layer of transparent conductive material thereover;
(ii) a second substrate having an outer surface and a non-planar inner surface opposing the planar inner surface of the first substrate, wherein the non-planar inner surface has an at least partial layer of transparent conductive material thereover;
(iii) an electrochromic medium disposed between the planar inner surface of the first substrate and the non-planar inner surface of the second substrate; and
(iv) wherein a center region of the electrochromic apodized aperture defines a pupilary region, and wherein the transparent conductive material on at least one of the inner surface of the first substrate (i) and the inner surface of the second substrate (ii) is electrically isolated in the pupilary region.

Abstract
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.
