A camera lens system, which uses a combination of lenses to focus light onto a sensor or film to capture an image. A microscope system, which includes lenses and mirrors to magnify an object for observation.
Short answer: Zacharias Jansen Long answer: Your question is not valid for 2 reasons: 1. You cannot "discover" something if it does not exist. You should be asking who invented it, not who found it laying around somewhere. 2. A "simple microscope" is not common terminology. Simple compared to an electron microscope? or simple compared to a compound microscope? What is typically referred to as just "microscope" is technically a compound microscope. A set of multiple lenses mounted in a desktop style that allows the compounding of magnification. A compound microscope is the standard microscope in any basic lab setting. Anything more "simple" than a compound microscope would not even really be a microscope, it would either be a telescope, or simpler than that is a magnifying glass (with a single lens) The inventor of the magnifying glass was: Roger Bacon The next step up is the telescope invented by: Zacharias Jansen The next step up is the "compound microscope" which was also invented by: Zacharias Jansen (this is the simplest form of what would be recognized as or named "microscope") If you wanted to go even "simpler" and define microscope as anything that magnifies, there were reading glasses around for thousands of years prior, and even "reading stones" which were lumps of polished glass used to magnify parchment in Egypt as far back as 7000 B.C. (inventor unknown). So it really depends on how you wish to refine your meaning of simple. The magnification of anything? There is no known inventor for reading stones, his name is lost to time. Or if you mean the first invented microscope that could examine things too small for a human eye to detect, that's a compound microscope. Thus if I am guessing your meaning correctly, you meant to ask this question: Question: Who invented the compound microscope? Answer: Zacharias Jansen
1. To provide a stable platform, so that the eye can more easily stay focused on the object. 2. To exclude external light sources.
An electron microscope has the greatest magnification among all types of microscopes. It can magnify specimens up to 2 million times, allowing for detailed views of extremely small structures.
The microscope was not "discovered" (that supposes it already existed but had not been found) but it was made. Quote: "Microscopes trace their history back almost 1200 years with Abbas Ibn Firnas's corrective lenses,[1] and it was Ibn al-Haytham's Book of Optics - written between 1011 and 1021 - that laid the foundation for optical research on the magnifying glass. Also, a device called the reading stone by an unknown inventor (thought to be Ibn Firnas) magnified text when laid on top of reading materials.[2] The first true microscope was made around 1595 in Middelburg, The Netherlands.[3] Three different eyeglass makers have been given credit for the invention: Hans Lippershey (who also developed the first real telescope); Sacharias Jansen; and his son, Zacharias. The coining of the name "microscope" has been credited to Giovanni Faber, who gave that name to Galileo Galilei's compound microscope in 1625.[4] (Galileo had called it the "occhiolino" or "little eye".)" From http://en.wikipedia.org/wiki/Microscope which is pretty trustworthy here.
The difference lies in the number of lenses that each microscope has. A compound microscope has 2 or more lenses, like those found in most science classrooms. A simple microscope uses only 1 lens.
A compound microscope uses 2 lenses (objective lens and eyepiece lens) along with a light source to magnify and view samples at high magnification.
A microscope uses two or more lenses to magnify living cells. Light passes through the specimen and through a series of lenses, allowing the user to see a magnified image of the cells. This technique is commonly used in biology and medicine for studying cells and tissues.
2 or more lenses.
A magnifying glass has one lenses and a compound light microscope has 2 lenses
A microscope has lenses and an adjustable stage. The lenses magnify the specimen being observed, while the adjustable stage allows for precise positioning of the specimen under the lenses.
A microscope uses lenses and light to magnify and view objects that are too small to be seen by the human eye. It can provide very high levels of magnification and resolution. In contrast, the human eye uses a complex system of lenses and the retina to perceive images of the external world.
A compound microscope has two lenses: the objective lens and the eyepiece lens. The objective lens is used to gather light from the specimen and create a magnified image, which is further magnified by the eyepiece lens for viewing.
A camera lens system, which uses a combination of lenses to focus light onto a sensor or film to capture an image. A microscope system, which includes lenses and mirrors to magnify an object for observation.
you must multiply the two lenses getting a total of 150X
The body tube of a compound optical microscope contains the ocular lens, also called the eyepiece lends, and the objective lens system which consists of one or more lenses.
A microscope with 2 eyepieces is called a binocular microscope. This type of microscope allows for viewing with both eyes simultaneously, providing a more comfortable and natural viewing experience. Binocular microscopes are commonly used in laboratories and educational settings.
