DESCRIPTION:Using focused ion-beam milling\, we demonstrate the micro-fabr
 ication of spherical and aspherical-profile mirrors of various footprints:
  circular\, square\, hexagonal\, rectangular. The very good control of the
  lateral and depth dimensions allow for control over the focusing properti
 es\, such that mirrors with diameters ranging from 1 to 10 m can be des
 igned and milled with focal lengths at the same position with respect to t
 he substrate surface. With modern lithographic systems and current generat
 ions of sample stages\, ion microscopes are ideal for producing master mol
 ds for stamping polymeric microlenses used in imaging detectors and other 
 light management applications.\n
