Hangzhou Shalom Electro-optics Technology Co., Ltd. 28.0mm Diameter, 63.5mm Focal Length，AR Coated Meniscus ZnSe Focusing Lenses for CO2 Lasers 2121-059

• Two types of lenses available: Plano-convex and Meniscus lenses • High-Quality CVD ZnSe grew in America, ensuring efficient power output and thermal resistance • AR coating with an excellent transmittance of T≥99.5%@10.6mm • Maximum diameter 200mm • Off-the-shelf and custom versions offered Zinc Selenide (ZnSe) is a popular material to be manufactured into focusing lenses for CO2 lasers. ZnSe is advantageous due to having the lowest absorption compared to other common CO2 laser transmitting materials, therefore particularly suitable for high-power applications. However, being relatively soft, ZnSe might be more sensitive to scratches. Hangzhou Shalom EO offers Plano-convex and Meniscus Zinc Selenide (ZnSe) Focusing Lens for CO2 laser systems and Versatile applications (e.g. Infrared Thermal Imaging, Military, Medical). Plano-convex ZnSe Lenses are the more conventional option, but for applications involving greater beam sizes and power densities, Meniscus ZnSe Lenses are more ideal in terms of lower spherical aberrations. For off-the-shelf versions, the specifications are: Diameters 12.0-38.1mm, Central Thicknesses 2.6-7.87mm, Focal Length 38.1-190.5mm with 10.6μm AR Coatings. For custom versions, the maximum diameter is 200mm, enabling applications of higher power output, and Broadband AR (BBAR) coatings may be furnished for Lenses orienting IR applications. Shalom EO selects CVD (chemically vapor deposited) ZnSe as the substrate material, which features extremely low bulk losses due to absorption and scatter, high resistance to thermal shock, and stability in virtually all environments. Additionally, Shalom EO incorporates the minimum-damage polishing technology during the coating process, and our AR coating ensures a high damaging threshold, high durability, and wiping resistance, with an excellent transmittance of T≥99.5%@10.6mm. Our experienced tech support is capable and willing to provide consultancy, which guarantees optimized interest for your laser systems and economized costs. If you have any other specific requirements, we are also able to offer an optimized design service of custom focusing lenses.
