Imported focal lens ZnSe

Imported focusing mirror lenses for laser machines, made of zinc selenide (ZnSe), are critical optical components in high-power laser systems. This material exhibits extremely high transmittance (>97%) and low absorption in the mid-to-far infrared band, particularly at wavelengths of 9.3μm and 10.6μm, enabling efficient transmission of laser energy. It also boasts good thermal stability and mechanical strength, allowing it to withstand high-power laser irradiation without easy damage.

These lenses typically employ precise optical designs such as plano-convex, double-convex, or Galilean structures. By optimizing surface shapes, they minimize aberrations, ensuring accurate laser beam focusing and high-quality beam spots. Some high-end products are additionally equipped with multi-layer anti-reflective coatings to further reduce reflection losses and enhance energy utilization.

Imported zinc selenide lenses are widely used in industrial laser processing (e.g., cutting, welding, marking), laser radar, and scientific research experiments, especially in scenarios requiring high-precision and high-power laser treatment. When using them, attention should be paid to wavelength matching, installation orientation, and power limits to ensure performance and safety.
