Laseroptics and LensesFocus-Ronar Lenses 1064 nm• Focussing lenses are optimized for​high precision applications, used in​laser systems for welding, cutting,​drilling and structuring.• This lens series is available in a number​of common focal lengths, ranging​from 56 mm to 120 mm.• They allow a maximum possible​entrance beam diameter of upto 35​mm.• The broadband coating is optimized​for 1064 nm with good inspection​performance at VIS wavelengths.• Additionally the Focus-Ronar lenses​can also be used at 532 nm.• With the design of three high quality​and optimized lens elements a​diffraction-limited focus is achieved.• It is possible to get one standardized​mechanical design for various focal​lengths.• Thanks to an outstanding mechanical​and optical precision the lenses can be​exchanged quickly and flexibly​withoutany adjustment.LaseropticsFocus-Ronar Lenses for 1064 nmEffective focal​length [mm] EFLClear​aperture Ø​[mm] CADia​met​er​[m​m] ​DLength[mm] LFlange focal​length [mm] ​FFLImage point diameter*[µm] (@input beam​25 mm)ØspotOrder-No56 34.0 41 h7 2​4​.​6 46.7 4.5 4401-487-000-2077 35.4 41 h7 1​8​.​9 72.2 6 4401-486-000-2090 35.4 41 h7 3​3​.​6 73.7 7 4401-490-000-20120 35.0 41 h7 2​4​.​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.
