Optics Mounting with Adhesives

Epoxy adhesives secure optical elements to holders securely and inexpensively and provide sufficient setting time for alignment while not delaying production.

Optical mirrors and lenses for copiers require accurate positioning which, during alignment and thereafter, fasten securely against vibration, mechanical and normal shaking, stresses on movement. An adhesive with these attributes must also have: - a setting time quick enough for Production use but sufficiently slow to permit alignment, - no appreciable change in value during setting, - an ability to flow into voids and across surfaces without migrating onto critical surfaces, - minimal outgassing, - sufficient body to fill gaps, - bond to glass, aluminum and various steels, and - retain flexibility sufficient to absorb them at expansion and shocks, but hard enough to maintain optics position. One commercially-available epoxy adhesive meeting these requirements is SCOTCH- WELD #2216 B/A (product of 3M Company).

In Fig. 1, the epoxy adhesive is applied along glue lines which retain a mirror between two locators and a bracket. Retainers in Fig. 2 eliminate threaded screw holes. All retaining hardware is eliminated in Fig. 3.
