Abstract:
A method of manufacturing a roof mirror, comprising the steps of.placing a first reflective surface and a second reflective mace on a precision fixture such that a first end of the first reflective surface meets a first end of the second reflective surface at a substantially 90 degree angle; optically checking the alignment of the reflective surfaces; applying an adhesive along a line where the first end of the first reflective surface and the first end of the second reflective surface meet; allowing the adhesive to set; verifying that the angle between the first and second reflective surfaces has remained substantially 90 degrees; applying an adhesive along a second end of the first reflective surface and a second end of the second reflective surface, wherein the second end of the reflective sure and the second end of the second reflective surface meet at a common point; applying a substantially rectangular glass substrate to the end of the first reflective surface and the second end of the second reflective surface; allowing the adhesive to set; and optically checking the alignment of the mirrors.
