The shrink fitter is a cylinder-shaped machine element which is made of plastic material. The f\u03b8 lens unit with the shrink fitter could converge the laser beam over a wide scanning width of 80mm. However the lager interference of shrinkage fit caused the lens deformations, much greater than the conventional limitation of surface irregularity of \u03bb/2. These lens deformations will deteriorate the laser beam spots. In addition to the effect of the interference, the beam spots will be very sensitive to lens decenters and the lens tilts. Thus we theoretically examined the effects of the lens deformations and the lens alignment on the laser beam spots of the f\u03b8 lens unit fixed by the shrink fitter. The limitation of the interferences and the lens misalignment were discussed.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d",
