Laser Focus Lens

Laser Focus Lens

This Laser Focus Lens adopts ZnSe materials and is used to focus laser beam. This particular lens has a wavelength of 10.6um. The objective of focusing the laser beam is to use the laser power for material processing, which is widely used with CO2 Laser Cutters, Laser Engraving and Cutting Machines.

This Laser Focus Lens adopts ZnSe materials and is used to focus laser beam. This particular lens has a wavelength of 10.6um. The objective of focusing the laser beam is to use the laser power for material processing, which is widely used with CO2 Laser Cutters, Laser Engraving and Cutting Machines.
Znse Co2 Laser Focus Lens are widely used for CO2 laser application because of its low absorption at infrared wavelengths as well as its visible transmission. ZnSe has a high capacity on the shock of thermal, make it become the best optical material in high-power CO2 Laser Systems. But its soft material is more easily scratch and highly refraction. So there is a need highly hardness film and reduce reflection film in surface coating to protect and get a high transmittance. ZnSe Focusing Lenses is including two types, ZnSe Singlet Plano-Convex Lenses and ZnSe Singlet Positive Meniscus Lenses.

ZnSe Singlet Plano-Convex Lenses (wavelength 10.6um):

Specifications:

  • Diameter Tolerance: +0/-0.13mm/+0.000’’ -0.005’’
  • Thickness Tolerance: ±0.25mm/±0.010’’
  • FL Tolerance: <±2%
  • Centration: <3 arc minutes
  • Clear Aperture >90%
  • Surface Figure <λ/2 per 1”Dia@632.8nm
  • Surface Quality 40-20 scratch and dig
  • AR/AR coating R<0.5% per surface @ 10.6um

ZnSe Singlet Positive Meniscus Lenses (wavelength 10.6um):

Specifications:

  • Diameter Tolerance: +0/-0.13mm/+0.000’’ -0.005’’
