Zinc Selenide (ZnSe) Aspheric Lens
Zinc Selenide (ZnSe) Aspheric Lens is a precision-engineered infrared optics designed to minimize spherical aberration.

The ZnSe Aspheric Lens can also enhance image quality in infrared (IR) systems.

With excellent transmission across the 600 nm to 16 µm spectral range, ZnSe aspheric lenses are widely used in high-power CO₂ laser optics, thermal imaging, and spectroscopy.

Their aspheric surface profile allows for superior focusing performance compared to standard spherical lens.

Why choose ZnSe lens?

  • 600 nm to 16 µm, ideal for mid-wave and long-wave IR applications.
  • The lens enables compact lens designs with shorter focal lengths.
  • Optimized for CO₂ laser systems.
  • It reduces spherical aberration, improves beam focusing, and enhances optical efficiency.
  • Chemically stable and compatible with protective AR coatings to reduce reflections.
