A grazing incidence telescope, often used in X-ray astronomy, employs a design where incoming X-rays strike the reflecting surface at very shallow angles, or "grazing" angles. This allows the telescope to focus high-energy X-rays that would otherwise pass straight through traditional optics. The mirrors are carefully shaped and aligned to maximize the reflection of these X-rays, enabling the observation of celestial phenomena that emit high-energy radiation. Examples include the Chandra X-ray Observatory and the XMM-Newton space telescope.

A reflecting telescope.
X-ray telescopes use grazing incidence mirrors to reflect and focus high-energy X-rays, which would be unable to be focused using traditional optical lenses. This design allows for better resolution and sensitivity for observing celestial objects that emit X-rays.
A reflecting telescope.
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
X-ray telescopes use grazing incidence to focus X-ray photons onto a detector. By reflecting the X-rays at a very shallow angle, these telescopes can overcome the limitations faced by traditional optical telescopes in detecting X-ray emissions from astronomical sources.
