Transparent ceramics
Many ceramic materials, both glassy and crystalline, have found use as optically transparent materials in various forms: bulk solid-state components (phone glass), high surface area forms such as thin films, coatings, and fibers. Ceramics have found widespread use for various applications in the electro-optical field including: optical fibers for guided lightwave transmission optical switches laser amplifiers and lenses hosts for solid-state lasers optical window materials for gas lasers infrared (IR) heat seeking devices for missile guidance systems IR night vision.
