Abstract This research aimed to study and compare the mechanical durability contamination resistance of organic spectacle lenses for everyday use, based on CR-39 poly(allyl diglycol carbonate) (PADC), from different manufacturers. The objects this are selected corrective three Each examined brand is represented by a reference uncoated lens other with types protective coating. sample has been ch...

Intense laser-produced plasmas generate bright, ultrashort bursts of accelerated ions. Reducing the required laser intensity and increasing repetition rate to high energy ions is important, mesoscopic particle targets are an attractive option address this issue. Newer experimental strategies measure ion energies their angular distribution needed in studies such systems. In paper, we outline a m...
