Gallium arsenide optical components
What are you looking for in Stock?
Gallium Arsenide (GaAs) is a tough, IR transmitting semi-insulating and insoluble material that shares many mechanical properties with Germanium. Gallium Arsenide is typically used where hardness and durability are desirable.
Gallium Arsenide is commonly used in thermal imaging, light emitting diodes, FLIR (Forward Looking Infrared) systems, CO₂ lasers, and as single-crystalline film for use in high efficiency solar cells. As Gallium Arsenide is extremely durable it can be used in harsh conditions. Gallium Arsenide is also used as the substrate for infra-red low-pass filter in spectroscopy.
Gallium Arsenide transmits over 40% between 2-15µm and has low absorbance over that spectrum. It has a hardness of HK750, slightly less than Germanium. The material is usually broadband antireflective coated to increase performance. Gallium Arsenide is typically used between 3-5μm and 8-12μm wavelengths.
