Does a compound microscope have only one lens?
no. a simple microscope has one lens. a compound microscope has two or more lens
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.
Why should you never rack downwards with the coarse focusing while you are looking down the microscope?
The object on the viewing stage is close to the lens of a microscope. Racking downward risks the lens touching the object and damaging either the object itself or the lens. Before moving the lens down, make sure you can see the lens and the object from the side of the microscope to void the two touching each other.
What does objective lenses in the microscope do?
A compound microscope has two lenses - the eyepiece lens and the objective lens. the objective lens(which is a convex lens) collects light and brings it to focus, creating an image. The eyepiece lens is placed at the focal point(the point at which light rays meetafter passing thru the convex lens). Thus we are able to see the magnified version of the image.
When 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.) Two decades later, Galileo Galilei built a compound microscope and changed the lens design lens (convex and concave lens).
Does a compound microscope have only one lens?
no. a simple microscope has one lens. a compound microscope has two or more lens
How does a compound microscope different from a simpel microscope?
a compound microscope has two or more lens while a simple microscope has only one lens
How does a two lens microscope work?

A light microscope that has two or more lenses is called a?
binoculars Binocular refers to having two ocular lens tubes. Compound microscope is any microscope with more than one lens.
How many lenses does a simple microscope have?
Robert Hookes microscope had either two or more lenses. a simple microscope has one lens in it.
Type of microscope made up of two or more lens?
compound microscope
Does a compound microscope have one lens?
Most microscopes have 4 to 5 lenses. The lenses are:The three Objects (which are the three things that you use to microscope)The lens that you you put your on.And the mirror lens.
The nature of the final image formed by a compound microscope?
The principle of image formation in a compound microscope states that the second lens magnifies the image formed by the first lens. The use of two lenses enhances the magnification of the image.
Type of microscope made up of two or more lenses?
The type of microscope that you are looking for is known as a "compound microscope."A pair of lenses includes the objective lens (one or more) and the eyepiece lens.
Why is the microscope called a compound microscope?
The compound microscope is called compound because the modifier compound means "two or more." A compound microscope has two or more lenses lenses. This is to be distinguished from a simple microscope which has one lens. Such a microscope is structurally equivalent to a magnifying glass, though not necessarily a hand held lens.

What is the function of the tube on the microscope?
A draw tube is one of two tubes that is in a monocular microscope. It is the tube that carries the eyepiece.
