Product Name: Duralens Focusing Lens
Product Description
The focusing lens is the last optic in the laser path, before it hits the workpiece. Its main role is to focus the laser beam to a specific focal length (FL) - depending on the application. Therefore, the focal length - that is dictated by the radiuses and curvatures of the lens - is its most important feature.
The focusing lens is normally made of Zinc Selenide (ZnSe) using an anti-reflective coating. Focusing lenses are either Plano-Convex or Meniscus. In order to ensure that your laser operates at maximum efficiency it is crucial to select the right lens. The type to be used with each machine is usually specified in the machine manufacturer's manual.
Ophir offers a wide range of standard and special lenses assuring that the most suitable and effective lens be fitted to your laser cutting machine.
Duralens™ Lenses - A Cut Above The Rest
The Ophir Duralens™, introduced in 1996, is manufactured using in house technologies (inspection of raw material, grinding, polishing, coating and quality control) that were developed to ensure high reliability and long life - saving you time and money. Ophir Duralens™ have superior Anti-Reflective (AR) coating, lower absorption, better surface quality (achieved by Ophir's micropolishing techniques) and maximum focus accuracy.
Black Magic™ Low Absorption Lenses
The Black Magic™ lenses are unique products offered by Ophir. The revolutionary black coating developed by Ophir enhances the resistance and performance of the lens.
Advantages of the Black Magic™ Lens:
Lowest absorption (lower than 0.15%).
Saves up to 20% of gas consumption.
Lasts twice the lifetime of a standard lens.
Best ability to withstand back splatter.
Less maintenance - extended lens cleaning intervals.
Black Magic™ lenses and black coated optical elements in the catalog are marked by the letters LA..
Meniscus Lenses
Meniscus lenses have one concave surface and one convex surface.
A meniscus lens creates a smaller beam diameter thus reducing the spherical aberration and beam waste when precision cutting or marking. The lens also provides a smaller spot size that creates the same power output in a smaller area. In order to achieve the smallest spot size the concave side of the lens is mounted face down, pointing towards the material being cut.
Although meniscus lenses are more expensive than Plano-Convex lenses, they offer a higher accuracy of the cut therefore increasing cutting speed by up to 5%.
Meniscus lenses are usually used by European customers and machine manufacturers (OEM's).
Plano-Convex Lenses
Plano-Convex lenses have one flat surface and one outward curving surface.
These lenses are more suitable for high turnover cutting applications and when cutting and welding certain materials (metals, wood, ceramics, plastics and composites) - when the cost is more important than the level of accuracy.
When cutting steel and other thick materials, a Plano-Convex lens provides a greater width of the cut enabling the laser's Oxygen assist to enter and ease the cutting process.
In addition, Plano-Convex lenses give a greater depth of field needed to maintain a taperless edge when cutting thicker materials. This kind of lens is more popular in American and Japanese machinery.
