Overview of Concave Mirrors
The document discusses optical concave mirrors, which are components with a high reflective coating on a concave surface. These mirrors can be spherical or cylindrical and are available with various coatings such as protective aluminum, silver, gold, and dielectric reflection coatings. Creator Optics (CNCO) offers manufacturing of these mirrors in different shapes, including plano-concave spherical or cylindrical, with customization options available.

Materials
The substrates for these mirrors can be made from materials like BK7, fused silica, float glass, BOROFLOAT, Pyrex, and sapphire.
