How was the compound microscope invented?
Zacharias Janssen and his son Johannes (Hans), spectacle makers in Holland, are usually credited with inventing the first compound microscope in about 1590. (Hans Lippershey, a spectacle maker in the same city, Middelburg, Netherlands, also claimed credit for the invention but was perhaps more instrumental in the creation of the telescope.) It was said that the Zacharias Janssen was experimenting with ways to improve spectacles for people who needed greater magnification to improve eyesight, but nothing more specific than simply experimenting with multiple lenses can be associated with how he invented the compound microscope. It is worth noting that at the same time experimentation by other spectacle makers and lens makers was leading to the discovery of the telescope, another optical instrument of two lenses. Two decades later, Galileo Galilei built a compound microscope and changed the lens design lens (convex and concave lens).
What did the telescope and barometer and microscope and thermometer help improve?
You guys are dumb
When was the first simple microscope invented?
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.More: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.
What is the function of a iris diaphragm in microscope?
The diaphragm reduces the light from under the stage which can improve the image contrast.

Antony van leewenhoek?
Anton van Leeuwenhoek was a Dutch scientist who made major contributions in the field of microbiology and in the advancement of the compound microscope. He is also referred to as the "Father of Microbiology." He was born in 1632 and died in 1723.
