Features:

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

GaAs - transparent in 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. To obtain superior transmittance, GaAs crystals are grown by Chemical Vapor Deposition process .

GaAs is polycrystalline material, demonstrates superior CO2 laser transmittance and is employed in the transmission optical components used in CO2 laser processing.

Note:

1.Avoid directly Touch the smooth surface when Take the lens，It's best to touch

with a finger glove or a soft paper towel，Avoid degrading performance due to greasy dirt.

2.The lenses should be placed lightly on soft paper to avoid surface damage.

3.Use medical alcohol cotton swab or soft paper towel, dip in alcohol, gently scrub

the surface, avoid strong scrubbing. It must be clockwise or counterclockwise to

wipe the whole lens at once.

OEM or ODM are both available:

Our company has a large number of standard parts in stock, clients can order based on product size, technical parameters, and we accept customized processing of ZnSe products, incoming processing, ZnSe window, ZnSe lens, ZnSe prism, etc.
