X-ray optics is a branch of optics. X-ray optics manipulates X-rays instead of visible lights in normal light optics and electron beams in electron microscopes (EMs). The lenses for visible light are made of transparent materials that can have a refractive index (or called index of refraction) significantly larger than 1 and the lenses for EMs are composed of magnetic lens , for X-rays the index of refraction is slightly smaller than unity.
