When was the first simple microscope invented?

Answer 1

Simple Answer:

The inventor of the first microscope is not recorded. The simple single-lens form of a microscope was in use by the 13th century by some accounts. The modern compound microscope was first developed in 1590 by the Dutch spectacle-makers Hans Janssen and his son Zacharias Janssen.

The first microscope was merely a single lens.

A single lens is termed a "simple microscope" but is commonly referred to as a magnifying glass.

The first use of the single lens to magnify is not recorded.

It is thought that magnification by a glass lens was known soon after glass was discovered thousands of years ago, but there is no record of its use for any purpose beyond a curiosity.

It is thought that around 1,000 AD use of the lens as a magnifying device was established, to this may be considered the time of the first microscope.

The invention of the first lenses in spectacles to improve vision was in Italy in the 13th century.

In 1590 the first modern microscope was created, the compound microscope.

A compound microscope is any microscope with two or more lenses.

The limitation of the quality of glass and the use of only two lenses made the first compound microscope only a limited improvement.

The invention of the compound microscope is attributed to the Dutch spectacle-makers Hans Janssen and his son Zacharias Janssen in 1590, but this is not with certainty.

About 1670, Antonie van Leeuwenhoek developed a series of simple, single lens, microscopes with substantially improved lenses and magnification of 250 times or more.

Answer 2

The first simple microscope was invented in the late 16th century by Zacharias Janssen and his father Hans Janssen, in the Netherlands. It consisted of a single convex lens and allowed for magnification of small objects.
