Hans Lipperhey is known for the earliest written record of a refracting telescope, a patent he filed in 1608. [ 1 ] [ 2 ] His work with optical devices grew out of his work as a spectacle maker, [ 3 ] an industry that had started in Venice and Florence in the thirteenth century, [ 4 ] and later expanded to the Netherlands and Germany.
A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses .
He is also known for designing dialyte based refracting telescopes, coming up with the Zerochromat retrofocally corrected refractor, including a folded 30-inch f/12 version he built in 1999. This refracting telescope is the largest ever built by an individual and the eighth-largest refractor ever built. [3] Wall died on 27 January 2018.

Notes on Hans Lippershey's unsuccessful telescope patent in 1608. The first record of a telescope comes from the Netherlands in 1608. It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October 1608 for his instrument "for seeing things far away as if they were nearby." [12] A few weeks later another Dutch instrument-maker ...
From this work he concluded that any refracting telescope would suffer from the dispersion of light into colours. He went on to invent a reflecting telescope (today known as a Newtonian telescope), which showed that using a mirror to form an image bypassed the problem. In 1671 the Royal Society asked for a demonstration of his reflecting telescope.

He also invented an improved version of the refracting telescope, the Keplerian telescope, which became the foundation of the modern refracting telescope, [13] while also improving on the telescope design by Galileo Galilei, [14] who mentioned Kepler's discoveries in his work.
