Optical Coating

Evaluate optical coating durability by checking adhesion, abrasion resistance, compatibility with the intended cleaning method, and resistance to the operating environment. Then confirm that the coated component still meets its agreed optical and surface requirements after testing. A useful durability claim identifies the test method, conditions, sample and acceptance criteria. A low-reflection coating can meet …

An AR coating curve is useful only when its wavelength range, reflection or transmission metric, coated surfaces, angle and polarization match the application. Learn how to compare laser-line and broadband AR coatings without mistaking a typical curve for a complete optical specification.

Optical coating is used in precision lenses, camera-related optics, industrial glass components, laser systems and other optical applications. It applies functional layers to a component’s surface to meet an optical requirement, such as controlling how the surface interacts with light. For a buyer, the starting point is the part’s role in the finished product and …
