3D printed lenses enable ultra-long-distance spectroscopy

Researchers at the University of Warsaw, Poland, have designed micrometre-sized lenses using a Direct Laser Writing (DLW) 3D printing technique. The 3D printed lenses can be fabricated on top of various materials, including fragile graphene-like materials. The research team, based in the Faculty of Physics, explains that the lenses can replace bulky microscope objectives that […]
