The amount of filtration of the x-ray beam is specified by and based on the voltage potential (keV) used to produce the beam. The thickness of filter materials is dependent on atomic numbers, kilovoltage settings, and the desired filtration factor.
However, in photography, the term UV filter can be also be misused as a filter that passes UV light while blocking other wavelengths in the light spectrum, in the same way the term IR filter is also sometimes misused.The correct names for such filters though, are UV pass filter and IR pass filter.V filters are used in sunscreens to protect skin or in photography to reduce the level of ultraviolet light that strikes the recording medium. Historically, photographic films were mostly sensitive to UV light, which caused haziness or fogginess, and in color films a bluish hue.
