The coating jig is a carrier used to fix glass, lenses, or wafers in the coating machine, such as Thin Film Coating Dome Jig, Dome Sectors, Dome Segments, Calotte segments, Coating Fixture, or Insert Rings.

A dome-shaped jig used in evaporators to hold substrates in vacuum for optical thin film deposition. High-precision shaped domes are essential for uniform film formation in the production of antireflective coatings and die clock filters. Deposition operations are generally used with substrate holding jigs.

Thin film optical coatings are critical for improving the performance of optical surfaces in a wide range of applications. They can improve visibility, enhance image quality, reduce reflectivity, and enhance durability, all of which contribute to improved performance and reliability.

Thin film optical coatings enhance/alter the performance of optics and photonics components and assemblies used in imaging systems, photonic integrated circuits, solar cells, laser, light-emitting diodes, light crystal displays, lithography, and micro-electromechanical systems (MEMS).
