MLL geometries. The left-hand views show the manufactured shapes of the lens and the right-hand views show the geometry usually used for experiments: (a) flat geometry, (b) tilted geometry, (c) stress-wedged geometry, (d) tilted stress-wedged geometry, (e) gradient-wedged geometry and (f) tilted gradient-wedged geometry. The geometries shown in (e) and (f) have not been used in the scope of this work and are discussed for comparison. In this scheme an incident beam is coming from the left side and would be focused to the right side. From a flat lens either a tilted or a stress-wedged MLL is obtained. The gradient-wedged MLL has to be manufactured from a dedicated deposition with a steep lateral thickness gradient. The arrows indicate possible changes between geometries.
