Abstract
A method of forming an optically transparent seal involves the steps of providing an uncured resinous material, adding a spacing media to the resinous material and curing the resinous material. The spacing media can have an index of refraction similar to that of the resinous or an antireflective coating provided thereon. A filler material can also be added to the resinous material.
Claims21
An electrochromic mirror system comprising:
- a mirror assembly containing a first transparent element and a second element spaced apart from said first transparent element, the side of said first transparent element confronting said second element having a layer of a transparent conductive material disposed thereon, and the side of said second element confronting said first element having a layer selected from the group consisting of a transparent conductive material and a reflective material disposed thereon, where, when said first element-confronting side is coated with said transparent conductive material, the side of said second element not confronting said first element has a layer of reflective material disposed thereon;
- an electrochromic media provided between said first and said second elements;
- a transparent seal having an optical transmission of over 50% surrounding and confining said electrochromic media between said first and said second elements;
- and
- where at least a portion of said seal is included in a visible reflective area of said mirror assembly, thereby increasing the field of view of said mirror system.

- a transparent seal having an optical transmission of over 50% surrounding and confining said electrochromic media between said first and said second elements;
- and
- a layer of a conductive material provided on at least a portion of the edges of said first and second elements and electrically connected to said layers on the sides of said first and second elements confronting one another;
- where at least a portion of said seal is included in a visible reflective area of said mirror assembly, thereby increasing the field of view of said mirror system, and where said first and second elements are assembled with zero offset.
