Abstract
An x-ray window can include a thin film that comprises boron. The thin film can be relatively thin, such as for example ≤200 nm. This x-ray window can be strong; can have high x-ray transmissivity; can be impervious to gas, visible light, and infrared light; can be easy of manufacture; can be made of materials with low atomic numbers, or combinations thereof. The thin film can include an aluminum layer. A support structure can provide additional support to the thin film. The support structure can include a support frame encircling an aperture and support ribs extending across the aperture with gaps between the support ribs. The support structure can also include boron ribs aligned with the support ribs.
