Abstract
It is shown that a multiple beam wedge plate interferometer can be use d in transmission mode to display accurately the lateral aberration cu rve of a collimating lens. Experimental results showing the sharpened fringes and a comparison with the computed lateral aberration curves a re given. Further, for larger shear, some new features are observed; t hese are explained by considering contributions of higher order terms in the Taylor's series expansion of the path function.
