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.
