Laseroptics and LensesFocus-Ronar Lenses 1064 nm• Focussing lenses are optimized forhigh precision applications, used inlaser systems for welding, cutting,drilling and structuring.• This lens series is available in a numberof common focal lengths, rangingfrom 56 mm to 120 mm.• They allow a maximum possibleentrance beam diameter of upto 35mm.• The broadband coating is optimizedfor 1064 nm with good inspectionperformance at VIS wavelengths.• Additionally the Focus-Ronar lensescan also be used at 532 nm.• With the design of three high qualityand optimized lens elements adiffraction-limited focus is achieved.• It is possible to get one standardizedmechanical design for various focallengths.• Thanks to an outstanding mechanicaland optical precision the lenses can beexchanged quickly and flexiblywithoutany adjustment.LaseropticsFocus-Ronar Lenses for 1064 nmEffective focallength [mm] EFLClearaperture Ø[mm] CADiameter[mm] DLength[mm] LFlange focallength [mm] FFLImage point diameter*[µm] (@input beam25 mm)ØspotOrder-No56 34.0 41 h7 24.6 46.7 4.5 4401-487-000-2077 35.4 41 h7 18.9 72.2 6 4401-486-000-2090 35.4 41 h7 33.6 73.7 7 4401-490-000-20120 35.0 41 h7 24.0 110.7 9.5 4401-420-000-20Technical data for Focus-Ronar lenses with awavelength of 532 nm are available on request.* The entrance beam diameter (Øbeam) and the imagepoint diameter (Øspot) refer to intensity 1/e 2 atGaussian illumination.
