how are spherical mirrors made??URGENT!!!!!!!!!!!!!!!!!!!!?
Please anybody tell me how are curved mirrors(concave/convex) made
this is how a normal mirror is made:
Most mirrors are made by applying a reflective coating to a suitable substrate. The most common such substrate is glass, due to its ease of fabrication, its rigidity, and its ability to take a smooth finish. The reflective coating is typically applied to the back surface of the glass, so that it is protected from corrosion and accidental damage. (Glass is much more scratch-resistant than most reflective coatings.)
The substrate is shaped, polished and cleaned, and is then coated. Glass mirrors are most often coated with silver or aluminium, implemented by a series of coatings:
1. tin
2. silver
3. chemical activator
4. copper + okhtak
5. paint
The tin is applied because the silver will not bond with the glass. The activator causes the tin/silver to harden. Copper is added for long-term durability.[8] The paint protects the coating on the back of the mirror from scratches and other accidental damage.
In some applications, generally those that are cost-sensitive or that require great durability, mirrors are instead made from a single, bulk material such as polished metal.
For technical applications such as laser mirrors, the reflective coating is typically applied by vacuum deposition on the front surface of the substrate. This eliminates double reflections and reduces absorption of light in the mirror. Cheaper technical mirrors use a silver, aluminium, or gold coating (the latter typically for infrared mirrors), and achieve reflectivities of 90–95% when new. A protective overcoat may be applied to prevent oxidation of the reflective layer. Applications requiring higher reflectivity or greater durability use dielectric coatings, which can achieve reflectivities as high as 99.999% over a narrow range of wavelengths.
but with Curved mirrors this is the story:
In a plane mirror, a parallel beam of light changes its direction as a whole, while still remaining parallel; the images formed by a plane mirror are virtual images, of the same size as the original object (see mirror image). There are also concave mirrors, where a parallel beam of light becomes a convergent beam, whose rays intersect in the focus of the mirror. Lastly, there are convex mirrors, where a parallel beam becomes divergent, with the rays appearing to diverge from a common intersection "behind" the mirror. Spherical concave and convex mirrors do not focus parallel rays to a single point due to spherical aberration. However, the ideal of focusing to a point is a commonly-used approximation. Parabolic reflectors resolve this, allowing incoming parallel rays (for example, light from a distant star) to be focused to a small spot; almost an ideal point. Parabolic reflectors are not suitable for imaging nearby objects because the light rays are not parallel.
