WebSep 1, 2016 · Optical contacting is a technique which takes advantage of short-range molecular attraction to bond two pieces of highly polished crystal together without the need for adhesive. Each sapphire tube, with inner diameter of 2.64 cm, has a 0.635 cm thick, 30 arcminute wedged sapphire window optically contacted to one end. react icons for vueThe use of optical contact bonding allows the production of a final product with properties as good as the bulk solid. This can include temperature and chemical resistances, spectral absorption properties and reduced contamination from bonding materials. See more Optical contact bonding is a glueless process whereby two closely conformal surfaces are joined together, being held purely by intermolecular forces. See more Intermolecular forces such as Van der Waals forces, hydrogen bonds, and dipole-dipole interactions are typically not sufficiently strong to hold two apparently conformal rigid … See more Since the method requires no binder, balsam or glue, the physical properties of the bound object are the same as the objects joined. Typically, glues and binders are more heat … See more Isaac Newton has been credited with the first description of conformal interaction observed through the interference phenomenon known … See more In addition to both surfaces' being practically conformal (in practice often completely flat), the surfaces must also be extremely clean and free from any small contamination that … See more Originally the process was confined to optical equipment such as prisms—the earliest examples being made around 1900.
