A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (bulging 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 optical devices such as reflecting telescopes that need to image distant objects, since spherical mirror systems, like spherical lenses, suffer from spherical aberration. One advantage that mirror optics have over lens optics is that mirrors do not introduce chromatic aberration.
Convex mirrors
A convex mirror, fish eye mirror or diverging mirror, is a curved mirror in which the reflective surface bulges toward the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. Such mirrors always form a virtual image, since the focal point (F) and the centre of curvature (2F) are both imaginary points "inside" the mirror, that cannot be reached. As a result, images formed by these mirrors cannot be projected on a screen, since the image is inside the mirror. The image is smaller than the object, but gets larger as the object approaches the mirror.
Tell me how does it feel when you look at your Self, don’t you tremble every time you need some Change? This time, I know, it’s cool to have a band, to get Some popularity, it’s trendy to succeed on something You don’t really like, I can’t take it any more your Filthy lies just suck! Whenever you look through your concave crystal, you Distort reality, defaced mankind cannot love every Thing they hate, when the fuck are you going to Fill that goddamn gap, you know it’s growing … and Tomorrow will be to late for your change. And I’m not a wise but I love the things I like to Do, so take my hand down to reality, catch the Things in their pure state, I wonder if you’ll ever Believe me. Whenever you look trough your concave crystal, you Distort reality, defaced mankind cannot love Everything they hate, When the fuck are you going to fill that goddamn Gap, you know it’s growing … and tomorrow will be To late for your change… Like always … always find a alibi to hide from
The central feature of the telescope is an exquisitely polished, concave primary mirror, 2.4 meters (7.9 feet) in diameter. The primary mirror sits beneath a smaller, secondary mirror that, connected by struts, sits at the peak of the telescope.
Reflector telescopes gather light with a concave parabolic mirror at the end of an open tube. The image collected by the mirror is sent to the eyepiece with a flat mirror that bounces the image outside the tube to the eyepiece.

Laurent Cassegrain improved upon Newton’s design in 1672 by using a concave primary mirror and a convex secondary mirror to reflect light back through a hole in the primary mirror to the eyepiece, enabling a long focal length in a compact tube.
