Thin Film Processing

Applications of Films

Nickel Electroformed mirrors, as formed, have relatively low reflectivity in the visible and ultra-violet regions of the spectrum and are subject to immediate oxidation upon exposure to air. Therefore a thin film deposition of some type is usually applied to the nickel substrate either by electrodepositing an enhancement metal or vacuum coating using a wide variety of materials.

Bright rhodium is generally electrodeposited over nickel and exhibits an average of 74% reflectance through the visible spectrum. Rhodium and other precious metals are electrodeposited utilizing state-of-the-art deposition equipment and controls, which provides consistent quality deposits as well as total adherence.

Electrodeposited rhodium also insures maximum durability along with exceptional corrosion resistance.Vacuum deposited thin film coatings are also available to enhance reflectivity in the visible as well as the infrared and ultra-violet spectral regions. By careful design, these high performance coatings will be tailored to enhance and maximize performance in many specific wavelength regions, especially the ultra-violet.

Substrate Size and Shape

Opti-Forms routinely deposits optical coatings ranging in size from a few inches in diameter to over fifty inches in diameter.Opti-Forms offers the unique ability to accurately deposit optical coatings onto complex geometries such as surface of revolution collection optics, as well as more conventional planar surfaces.
