Laser Beam Expander for CO2 Laser / BE-10600-A
This is a beam expander for CO2 Laser (wavelength: 10.6μm) made of zinc selenide (ZnSe) lens. It will be used in laser marking system and so on.
Diopter correction function is provided, customer can fine-tune the collimated beam.Because it is a beam expander type of the Galilean, it is compact and has good aberration characteristics.
Since the lens of zinc selenide has an anti-reflection coating, loss of light intensity is kept low.
Important： Treatment of ZnSe optics
ZnSe (Zinc selenide) is Poisonous and harmful substance classified as legal, depending on the specifications, the certificate of delivery may be required for acquisition of Poisonous and harmful substances.In addition, ZnSe Optics disposal after use is prohibited in general.
