75mm Diameter 200mm Focal Length Concave Mirror
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.
Concave mirrors bulge inward to create real images by converging rays. This reflects light inward to one focal point; therefore they are used to focus light. Unlike convex mirrors, concave mirrors show different image types depending on the distance between the object and the mirror creating an incredible characteristic in that the image location and quality is completely independent of the wavelength. This allows the design of very wide spectral range instruments and does allow a system that will work in the IR to be aligned using visible light.
Metal coated mirrors are made of protected UV Enhanced Aluminium, Aluminium (Al), protected Gold (Au), protected Silver (Ag) coatings.
