A complete plano-convex ingot has been uncovered in Sweden for the first time.

From Science Daily

"What is new in this study- is that we went a step further, and by combining the obtained data with known historical and archaeological information, we managed to propose a historical context, for both the unique Särdal plano-convex ingot and the rod ingots from the Iława Lakeland area in northeastern Poland. Given the astonishing similarity of the metal composition in all those artifacts we also manage to strengthen earlier hypotheses about contacts and networking in the Baltic area during the Nordic pre-Roman Iron Age," says Serena Sabatini.

From Science Daily

Plano-convex ingots are most often made of copper, although some are formed from bronze or other copper-based alloys.

In Optica, Optica Publishing Group's journal for high-impact research, these researchers demonstrate the new method by using it to make a millimeter-sized plano-convex optical lens with an imaging performance similar to a commercially available glass lens.

From Science Daily

To test the new method, the researchers first created a simple plano-convex lens and showed that it had an imaging resolution comparable to a commercial glass lens with the same physical dimensions.
