2. Curved mirror - Wikipedia

   en.wikipedia.org/wiki/Curved_mirror

   A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Most curved mirrors have surfaces that are shaped like part of a sphere, but other shapes are sometimes used in optical devices. The most common non-spherical type are parabolic reflectors, found in ...

3. Kozyrev mirror - Wikipedia

   en.wikipedia.org/wiki/Kozyrev_mirror

   A Kozyrev mirror (Russian: Зеркало Козырева, romanized: Zerkalo Kozyreva), in Russian esoteric literature from the 1990s, is a pseudoscientific device made from long sheets of aluminum (sometimes from glass, or a reflecting, mirror-like material) curled into a cylindrical spiral. It is alleged to focus different types of ...

4. Cassegrain reflector - Wikipedia

   en.wikipedia.org/wiki/Cassegrain_reflector

   The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture. This design puts the focal point at a convenient ...

5. Claude glass - Wikipedia

   en.wikipedia.org/wiki/Claude_glass

   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. Claude glasses have the effect of reducing and simplifying the colour and ...

6. Schmidt camera - Wikipedia

   en.wikipedia.org/wiki/Schmidt_camera

   The Schmidt camera was invented by Estonian-German optician Bernhard Schmidt in 1930. [1] Its optical components are an easy-to-make spherical primary mirror, and an aspherical correcting lens, known as a Schmidt corrector plate, located at the center of curvature of the primary mirror. The film or other detector is placed inside the camera, at ...

7. Side-view mirror - Wikipedia

   en.wikipedia.org/wiki/Side-view_mirror

   Large side mirror from a Honda Ridgeline with vortex generators to reduce wind noise. A side-view mirror (or side mirror), also known as a door mirror and often (in the UK) called a wing mirror, is a mirror placed on the exterior of motor vehicles for the purposes of helping the driver see areas behind and to the sides of the vehicle, outside ...
