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 following advantages:
-processing of increased thicknesses at a given power
-improved kerf quality
-elimination of upper and lower surface dross
-reduced assist-gas usage
-improved process control
ICC proposed and has been using a novel approach in fabrication of DFL, which in particular did allow us to create DFL of cylindrical shape.

ICC supplies cylindrical DFL with the following EFL combination:127&254mm and 169&254mm. Alternative sizes and custom designs are manufactured upon request.
A line of ZnSe cylindrical lenses that are used to focus or expand laser beams for applications such as optical metrology, laser scanning, spectro-scopy, and laser diode systems is available from Laser Research Optics of Providence, Rhode Island.
Laser Research CO2 Cylindrical Lenses can be used to focus a laser beam into a thin line or expand the output of a laser diode into a symmetrical beam in one axis only. They are available in 1" and 2" dia. sizes with ±0.005" CT and feature focal lengths from 5" to 30" with ±0.5% tolerance.
Offered with A/R coatings that typically provide 0.5% max. reflectance per surface at 10.6 µm and normal AOI, Laser Research CO2 Cylindrical Lenses have a 60-40 scratch-dig surface finish and 1 fringe surface accuracy at 633 nm. Centration error on these ZnSe lenses is 5 Arc-mins. max.
Laser Research CO2 Cylindrical Lenses are priced according to configuration and quantity. Price quotations are available upon request.
