GaAs Laser Focus Lens Dia 20mm FL 38.1mm

Gallium Arsenide (GaAs) is the material of choice in dirty or high-splatter environments. Its relatively high hardness helps repel debris particles. Its high thermal conductivity helps transmit heat away from embedded particles.

• GaAs are used for optical windows, lenses, mirrors, prisms, optical blanks, plates, disks, sheets, and slabs, particularly for infrared applications.

• GaAs are transparent in a wide spectral range from yellow (visible) to far IR. GaAs material is a chemically inert, non-hygroscopic, and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock, and stability in virtually all environments, easily machined. GaAs crystals are grown by the Chemical Vapor Deposition process to obtain superior transmittance. GaAs is a polycrystalline material that demonstrates superior CO2 laser transmittance and is employed in transmitting optical components used in CO2 laser processing.
