A coated optical component includes an optical component and a conformal coating. The optical component is crystalline calcium fluoride and the conformal coating is an atomic layer deposition (ALD) coating in contact with a surface of the optical component. The ALD coating includes a metal fluoride ALD coating having a metal different from calcium. The ALD coating can include other metal oxide or metalloid oxide ALD coating layers. The method for making the coated optical component includes depositing an atomic layer deposition (ALD) coating on a surface of the optical component, where the ALD coating can be a metalloid oxide, a metal oxide, a metal fluoride having a metal that is different from calcium, or combinations of these. Sulfur hexafluoride is used as a fluorine source in the ALD process.

Atomic layer deposition methods for coating an optical substrate with magnesium fluoride. The methods include two primary processes. The first process includes the formation of a magnesium oxide layer over a surface of a substrate. The second process includes converting the magnesium oxide layer to a magnesium fluoride layer. These two primary processes may be repeated a plurality of times to create multiple magnesium fluoride layers that make up a magnesium fluoride film. The magnesium fluoride film may serve as an antireflective coating layer for an optical substrate, such as an optical lens.

A vehicle includes a body of the vehicle and a sensing system coupled to the body. The sensing system includes optical componentry and a glass material, where the glass material at least in part houses the optical componentry and the glass material is at least partially transparent to light at the wavelength of the optical componentry. Further the glass material has mechanical and performance properties that allow the sensing system to be positioned particularly low on the vehicle, at a position that may be of higher risk for damage from debris.

The disclosure is directed to a highly reflective multiband mirror that is reflective in the VIS-NIR-SWIR-MWIR-LWIR bands, the mirror being a complete thin film stack that consists of a plurality of layers on a selected substrate. In order from substrate to the final layer, the mirror consists of (a) substrate, (b) barrier layer, (c) first interface layer, (d) a reflective layer, (e) a second interface layer, (f) tuning layer(s) and (g) a protective layer. In some embodiments the tuning layer and the protective layer are combined into a single layer using a single coating material. The multiband mirror is more durable than existing mirrors on light weight metal substrates, for example 6061-Al, designed for similar applications. In each of the five layer types methods and materials are used to process each layer so as to achieve the desired layer characteristics, which aid to enhancing the durability performance of the stack.
