Soft lithography with surface tension control is used to microfabricate extremely efficient solid immersion lenses (SILs) out of rubber elastomeric material for use in microscope type applications. In order to counteract the surface tension of the mold material in a negative mold that causes creep on...http://www.google.es/patents/US7042649?utm_source=gb-gplus-sharePatente US7042649 - Microfabricated rubber microscope using soft solid immersion lenses
