    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.
