Born in The Hague around 1585 to Hans Martens and Maeyken Meertens. Grew up in Middelburg, Netherlands, as a street seller. Worked as a spectacle maker from 1616, possibly taking Lowys Lowyssen's tools. Moved to Arnemuiden in 1618 due to counterfeiting activities
Optical instruments have a principal resolution limit due to diffraction physics. Resolution is proportional to wavelength and inversely proportional to aperture. Small apertures (e.g. f/22) are limited only by diffraction
