Metallic Coated Mirrors (Al, Ag, Au)
other sizes and shapes are available. Metallic reflective coatings are delicate and require care during cleaning. Clean and dry pressurized gas can be used to blow off loose particles, then clean, deionized water, a mild detergent can be used. Gentle cleaning with a swab is recommended Substrates: See "Lenses-Chapter" for the size of Plano-Concave or Plano-convex shape

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
