WebMar 1, 2004 · Solution-Assisted Optical Contacting A modified version of a conventional optical-contact procedure has been found to facilitate alignment of optical components. The optical-contact procedure (called simply optical contacting in the art) is a standard means of bonding two highly polished and cleaned glass optical components without using … WebSecuring a prism in place involves one of two methods: blocking and contacting. Blocking entails arranging the prism in a metal tool with hot wax. Contacting, on the other hand, is an optical bonding process done at room temperature where two clean glass surfaces are fastened together simply through their Van Der Waals interaction.

The 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. Later the … See more • Adhesion – Molecular property • Cohesion (chemistry) – Chemical property of like molecules sticking together • Gauge block – System for producing precision lengths by stacking … See more WebAs with ACB, optical contacting is performed by bringing two highly polished surfaces into close contact. However, optical contacting relies on molecular bonds (specifically, van der Waals forces), while ACB is based upon much stronger, covalent atomic bonds. how to start a used clothing export business
