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. ...
It is named after Paul Kirkpatrick and Albert Baez, the inventors of the X-ray microscope. [1] Although X-rays can be focused by compound refractive lenses, these also reduce the intensity of the beam and are therefore undesirable. KB mirrors, on the other hand, can focus beams to small spot sizes with minimal loss of intensity.
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 ...
Round convex mirrors called Oeil de Sorcière (French for "sorcerer's eye") were a popular luxury item from the 15th century onwards, shown in many depictions of interiors from that time. [3] With 15th century technology, it was easier to make a regular curved mirror (from blown glass) than a perfectly flat one.
A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...
Claude Lorrain mirror in shark skin case. A Claude glass (or black mirror) is a small mirror, slightly convex in shape, with its surface tinted a dark colour. Bound up like a pocket-book or in a carrying case, Claude glasses were used by artists, travelers and connoisseurs of landscape and landscape painting.
