ZnSe and GaAs Focus Lens (Laser Lens for Laser Machines)
The GaAs focus lens is a CO2 Laser mirror widely used in laser cutting machines, laser engraving machines, laser marking machines and more. We offer plano-spherical GaAs focal lens and a crescent-shaped GaAs focal lens to meet market demands.
We use US imported CVD ZnSe with a low absorption and double sided, anti-reflection capabilities to enable the ZnSe focus lens to withstand a high laser power density and have a transmittance of 99.5% in a 10.6mm wavelength that is common to CO2 Laser processing industry applications.
In addition, thanks to the optimized design in terms of diffraction and aberrations, our ZnSe focal lens' spot diameter reaches its minimum under conditions of the same focal length with other focal lenses.
Our ZnSe focus lens has a solid surface coating and can be scrubbed.
