24 Jan 2014 Jenoptik has added to its successful Silverline F-Theta product line new broadband F-Theta lenses with less absorption for high power diode laser applications. These lenses are covering a wavelength range of 900 to 1100 nanometers with high transmission performance. The specially developed anti-reflection coating is optimized for high transmission for the designated wavelength range. In addition, minimal absorption in the optics is key to high performance lenses for high-power laser applications. These lens properties ensure constant process parameters for the entire scanning fields and are particularly advantageous for applications with high-performance diode lasers running as high as the kilowatt range.
The first two versions of F-Theta broadband lenses are available for applications operating with focal lenghts of 160 and 255 millimeters together with a minimum spot diameter of down to 22 micrometers for single mode condition. Scanning fields with diagonals up to 160 millimeters can be processed. Application results from customers show very high performance with minimal thermal focal shift.
The lenses are advantageous for galvanometer scanner-based processes, such as those applied in mechanical engineering and car manufacturing, to process metals, sheet metal, and composite fibre materials.
