Breakthrough coating technology makes 3D printed lenses anti-reflective

Researchers from the University of Stuttgart have developed a new, reliable method of coating 3D printed lenses with anti-reflective coatings. Dubbed low-temperature thermal atomic layer deposition (ALD), the approach is capable of coating multi-lens systems as small as 600 microns in diameter, and helps to minimize the light lost due to reflections between lens interfaces.
