A mirror is an object with a surface that has good specular reflection and is smooth enough to form an image. II-VI provides many types of mirrors, including plane mirrors (meaning the surface is flat) and curved mirrors (meaning the surface is curved, producing magnified or de-magnified images, focusing light, or distorting the reflected image). Metal coatings can include gold, silver, or aluminum. II-VI produces metal-coated mirrors that offer a good combination of performance and value for general-purpose applications. These mirrors operate over a very broad spectral range from UV to visible and visible to near- and mid-IR. They are relatively insensitive to angle of incidence and polarization.
