1. A chucking system to hold a substrate, said chucking system comprising:
a chuck body having a side with a pair of spaced-apart support regions extending therefrom terminating in a plane, said pair of spaced-apart support regions having a recess defined therebetween, with a portion of said chuck body in superimposition with said recess being transparent to radiation having a predetermined wavelength, with said chuck body being defined between said side and said plane.
