20 Jan 2012 At SPIE Photonics West 2012, Jenoptik will introduce new F-Theta Fused Silica Lenses for laser powers up to 2 kW
The High-Power series of Jenoptik´s F-Theta-JENar® Lenses is now extended with new F-Theta full fused-silica lenses for optimized performance in multi-kW laser applications. This new lenses are used for operations at a wavelength range of 1030 up to 1080 nanometer with focal lengths of f=160 and f=255 milimeter. The lenses complete the F-Theta JENar® full fused-silica family for high-power fiber and disk lasers.
The F-Theta full fused-silica lenses with diffraction-limited design feature high spot uniformity over the entire scan range and provide a distinctly higher damage threshold in combination with just a minimum focal shift, even without active cooling. Its coatings and lens materials have been specifically optimized for fused-silica optics and enable only low absorption for applications with newest generation of multi-kW fiber lasers and disk laser.
In future an additional choice of F-Theta fused-silica lenses is planned for different applications with high-brilliant laser beam sources. Furthermore Jenoptik offers a wide range of standard
JENar® F-Theta lenses including models for 1064 nm, 532 nm, 355 nm and 266 nm.
In order to find uncompromising solutions for customer specific applications, Jenoptik also offers custom development of complete optical systems, lenses or individual components, especially for applications in laser material processing – from the formation of an intensity beam profile to the splitting of high-intensity laser beam.
