Designing & performing an accurate method for accurate adjustment of tilt and de-center in lenses in an optical system for quality enhancement

in this research an accurate method for adjustment of tilt and de-center in an optical system is presented. In this method exit spherical wave-front of and autocollimator and objective is used. De-center and tilt of each lens are adjusted through reflecting spherical wave-front from the front surface and back surface of each lens, respectively. Adjustment of decenter and tilt for all lenses is performed while the performance of system is enhanced considerably.
