lenses, windows, mirrors, filters and prisms
Used for lenses and beam splitters and provides an alternative to ZnSe in medium to high power CW CO2 laser systems. Gallium Arsenide is most useful in applications where toughness and durability are important. Its hardness and strength make it a good choice where dust or abrasive particles tend to build up on or bombard the optical surfaces. The material is non-hydroscopic , safe to use in laboratory and field conditions and is chemically stable except when in contact with strong acids.
