Dual-focus lens

Dual-focus lenses (DFL) are a revolutionary new type of lens for CO₂ laser cutting.

DFL are intended to be used as a direct replacement for conventional lenses in some industrial laser systems and applications. The basic principal of the lenses coming from their title lies in existence of a couple of focal points. Complex design of these lenses allows to distribute an incident laser energy and deliver its calculated fraction into a secondary (lower) focus.

 Especially designed to assist in a range of thick-section cutting jobs such lenses give the followings advantages:

• processing of increased thicknesses at a given power
• increased process speed
• improved kerf quality
• elimination of upper and lower surface dross
• immediate cut-initiation
• reduced assist-gas usage
• improved process control

Tydex proposed and has been using a novel approach in fabrication of DFL, which in particular did allow us to create DFL of cylindrical shape.

A specification below presents standard product. Custom-made sizes and specifications are available as well. Non-standard lenses can be designed and proposed upon certain RFQ.
