Abstract
A method of bonding an optical element (12) to a support (10) requires the formation on the support of a thin pad (11) of material of substantially the same dimensions as the base of the optical element. The material of the pad is one to which the adhesive to be used will not adhere. The optical element (12) is positioned on the pad (11) and a fillet of the adhesive (13) is applied around the base of the element, in contact with both the base of the element and with the support. As a modification, an aperture (14) may be formed in the pad (11) and filled with a rapid-setting adhesive (15) to secure the element in position while the fillet of adhesive is applied.
