Laser ZnSe Spherical Lens

  • Dimension: 1-150mm
  • Surface Accuracy: 60/40
  • Size Tolerance: +/- 0.1mm
  • Coating: Optional

The Laser ZnSe Spherical Lens is a spherical optical lens fabricated from high-purity zinc selenide (ZnSe) crystals.

It is specifically designed for laser systems and is particularly suitable for the mid-infrared laser band. Unlike traditional glass lenses.

The ZnSe material has extremely low absorption for mid-infrared lasers and covers the key laser wavelengths.

The Material of the Spherical Lens

Zinc selenide (ZnSe, Zinc Selenide) is an important optical crystal material, with a wide transmission range from visible light to far-infrared wavelengths (approximately 0.5 – 20 μm).

ZnSe has a low absorption rate and high transmittance, and also possesses good thermal stability and mechanical properties.

Therefore, people often use it in infrared windows, lenses, prisms and other infrared optical components.

Common applications include thermal imaging systems, infrared imagers, laser optical systems and medical equipment.

Due to its relatively soft nature (Mohs hardness approximately 2.25), people should be careful during processing and use.

Key Features of ZnSe Spherical Lens

  • Broad Transmission Range: 0.5 – 20 μm, ideal for IR systems.
  • Low Absorption at 10.6 μm: Excellent for high-power CO₂ laser applications.
  • High Precision Surface Quality: Minimizes scattering and distortion.
  • Customizable Sizes and Curvatures: Available in plano-convex, bi-convex, plano-concave, and bi-concave designs.

 

Applications

  • CO₂ Laser Systems: Focusing and beam shaping.
  • Thermal Imaging & IR Cameras: Enhancing imaging performance in the infrared band.
  • Medical Equipment: Laser surgery and diagnostic devices.
  • Industrial & Military Use: Cutting, welding, and infrared sensing systems.

 

With high transmission, low absorption, and precision optical performance, the Laser ZnSe Spherical Lens is essential components for CO₂ lasers and infrared systems.
