ZnSe Focusing Lenses for CO2 Lasers
Versatility:
Plano-Convex Lenses: Conventional choice for general applications.
Meniscus Lenses: Ideal for larger beam diameters and higher power densities due to lower spherical aberrations.
Material Benefits:
ZnSe (Zinc Selenide):Wide transmission range (600-16000nm). Low absorption at 1060nm, suitable for high-power CO2 lasers.
GaAs (Gallium Arsenide):
Higher hardness and greater thermal endurance.
Recommended for dirty or high-splatter environments.
Quality and Coating:
Made from CVD ZnSe grown in the USA, featuring low bulk losses, high resistance to thermal shock, and stable properties.
AR coatings ensure high transmission (T≥99.5%@10.6μm), high damage threshold, durability, and wiping resistance.
Minimum-damage polishing technique enhances performance and longevity.
Custom Options:
Off-the-shelf specifications: Diameters 12.0-38.1mm, Central Thicknesses 2.6-7.87mm, Focal Lengths 38.1-190.5mm with 10.6μm AR Coatings.
Custom specifications: Maximum diameter up to 200mm for higher power handling.
Design services available for optimized mirror design and cost-effectiveness.
Applications: Laser Processing, High-Power Laser Systems, Versatile Industrial Use, etc.
Focusing lenses are crucial components of CO2 lasers, used in various laser processing applications such as cutting, punching, welding, engraving, and more. Kingwin Optics offers two types of focusing lenses: plano-convex and meniscus lenses, both made from Zinc Selenide (ZnSe).
