Off The Shelf ZnSe Focusing Lenses for CO2 Lasers
Focusing lens is an indispensable part of the CO2 laser processing systems and other kinds of light converging applications. Zinc Selenide (Chemical formulae ZnSe, a crystal material of HIP polycrystalline cubic structure) lenses is the prior choice for high power CO2 laser systems due to its particularly low absorption for the 1064nm light. Shalom EO selects CVD (chemically vapor deposited) ZnSe grown in America, which features extremely low bulk losses induced by absorption and scatter, exceptional homogeneity, high thermal shock durability, and stability under harsh operating conditions. The relatively high refractive index of Zinc Selenide implies that anti-reflection coatings are crucial for ZnSe lenses, correspondingly, our AR coating ensures a high damaging threshold, high durability, and high abrasion-resistance, with an excellent transmittance of T≥99.5%@10.6mm.
The ZnSe Focusing Lens for CO2 Lasers are available in two forms: plano-convex and meniscus lenses in Shalom EO. Typically the plano-convex lenses are a more economical option for applications with moderate requirements, while the meniscus lenses have reduced spherical aberration and higher energy density, therefore is recommendable for applications necessitating more precision.
Both custom and standard modules are accessible in Shalom EO.
