We used a TruMicro 2024 by TRUMPF delivering bursts of intense ultrashort laser pulses with an individual pulse energy of up to 10 μJ, an intraburst pulse separation of 20 ns and a burst repetition rate of 200 kHz.
Optical contact bonding - Wikipedia
WebAn optical contact is meant to be an interface where the optical properties are close to perfect, i.e., without significant deviations from a perfectly clean and flat interface. Such a … WebSep 22, 2024 · The contact points were all on a common side of the template. The entire contacting jig was tilted at about 30°. Thus, when the isopropanol was applied, each optic … crypt of the necrodancer megamix

WebTotal Eye Care offers a wide variety of cutting-edge ophthalmic services and delivers them with excellent customer service. Our goal is to keep your eyes looking and seeing their … 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 WebContact; Design and Engineering; High Aspect Ratio Optics; Innovative Products.
