1 SACHARIAS JANSEN MIKROSKOP

2 a Dutch spectacle-maker from Middelburg He was born in 1580 in Hague His name is often written as – Zacharias Jansen – Zacharias Janssen – Sacharias Jansen He had a lot of problems with law He died in 1638 Invetions: 1.Telescope 2.Microscope

3 MIKROSCKOPE a single-lens (simple) Janssen invented it with the help of his father in 1595 The patent was denied origin of the microscope is a matter of debate Construction : – 2 tubes that gave a magnification of 10 X – the lens : bi-convex and plano-convex

4 USES Marcelo Malpighi - analysis of biological structures Antoni van Leeuwenhoek - discovered red blood cells and spermatozoa Nowadays, there’s a lot of types of microscopes and they are important for science explorations. Lenka Kunikova VII.BA Danica Pappova II.E GLS Trencin - SLOVAKIA
