The oldest telescope in the world

Archaeologists in the Netherlands have recently discovered telescopes that date back to the early 17th century and are thought to be the oldest in the world while digging a train tunnel in the city.

The Netherlands Times said the telescope was originally speculated to be a rusty tin tube and possibly a magazine. The specialist group of the Boerhaven Museum in Leiden confirms this is a telescope after closer observation and research. The telescope could have been built before 1650. The lab test results showed that it had a magnification of 5 times the object.

"In this case, this is the oldest telescope in the Netherlands, and maybe even the oldest in the world," said science history professor Albert van Helden, an expert in optics. good.

Helden believed that the telescope could be rusty by being made of tin. Glass types made of copper, commonly used in France or Italy in later stages, are less likely to encounter this phenomenon.

The magnification of a telescope is not large enough to be used for military purposes and can only be used in a residential community.

The telescope was invented in 1608 by a eyeglasses manufacturer in Middelburg, the Netherlands. The period was determined to preserve the oldest observation instruments in the Netherlands from the second half of the 17th century.
