2. Kirkpatrick–Baez mirror - Wikipedia

   en.wikipedia.org/wiki/Kirkpatrick–Baez_mirror

   A Kirkpatrick–Baez mirror, or simply KB mirror, focuses beams of X-rays by reflecting them at grazing incidence off a curved surface, usually coated with a layer of a heavy metal. It is named after Paul Kirkpatrick and Albert Baez , the inventors of the X-ray microscope .

3. X-ray optics - Wikipedia

   en.wikipedia.org/wiki/X-ray_optics

   One of the mirrors of XRISM made of 203 foils. X-ray mirrors can be made of glass, ceramic, or metal foil, coated by a reflective layer. [1] The most commonly used reflective materials for X-ray mirrors are gold and iridium. Even with these the critical reflection angle is energy-dependent. For gold at 1 keV, the critical reflection angle is 2. ...

4. List of largest optical reflecting telescopes - Wikipedia

   en.wikipedia.org/wiki/List_of_largest_optical...

   This table does not include all the largest mirrors manufactured. The Steward Observatory Mirror Lab produced the 6.5 metre f/1.25 collimator used in the Large Optical Test and Integration Site of Lockheed Martin, used for vacuum optical testing of other telescopes. Segmented mirrors are also referred to as mosaic mirrors. Single mirrors are ...

5. Corner reflector - Wikipedia

   en.wikipedia.org/wiki/Corner_reflector

   Therefore, the ray direction goes from [a, b, c] to [−a, b, c] to [−a, −b, c] to [−a, −b, −c], and it leaves the corner reflector with all three components of direction exactly reversed. The distance travelled, relative to a plane normal to the direction of the rays, is also equal for any ray entering the reflector, regardless of ...

6. Curved mirror - Wikipedia

   en.wikipedia.org/wiki/Curved_mirror

   The mirror equation and magnification equation can be derived geometrically by considering these two rays. A ray that goes from the top of the object through the focal point can be considered instead. Such a ray reflects parallel to the optical axis and also passes through the image point corresponding to the top of the object.

7. Spin casting (mirrors) - Wikipedia

   en.wikipedia.org/wiki/Spin_casting_(mirrors)

   Pioneered by Roger Angel at the Steward Observatory's mirror lab, this makes large (8.4 metres or 28 feet) thin parabolic mirrors by spinning the oven as the glass is melted and cooled. The term is applied to the fabrication of large telescope mirrors, where the natural paraboloid curve followed by the molten glass greatly reduces the amount of ...
