What is the function of the object lens in the microscope?
It is an optical instrument that gathers light from the object being observed and focus the light rays to produce a real image. They are also called objectives. In microscopes, lenses are found at the bottom near the sample. They are mainly used at telescopes, microscopes and cameras.
Who invented the microscope in 1656-1930?
The first microscope was made around 1595 in Middelburg, Holland. Three different eyeglass makers have been given credit for the invention: Hans Lippershey (who also developed the first real telescope); Hans Janssen; 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. (Galileo had called it the "occhiolino" or "little eye".) The most common type of microscope-and the first to be invented-is the optical microscope. This is an optical instrument containing one or more lenses that produce an enlarged image of an object placed in the focal plane of the lens(es). There are, however, many other microscope designs. "Microscopes" can largely be separated into three classes: optical theory microscopes (Light microscope), electron microscopes (e.g.,TEM), and scanning probe microscopes (SPM). Optical theory microscopes are microscopes which function through the optical theory of lenses in order to magnify the image generated by the passage of a wave through the sample. The waves used are either electromagnetic (in optical microscopes) or electron beams (in electron microscopes). The types are the Compound Light, Stereo, and the electron microscope.

The objective lens on microscope?
Used in conjunction with the eyepiece lens, the objective lens is what gives an optical microscope its ability to produce magnified images. There are normally three to four objective lenses on microscopes, ranging from 4X to 100X magnification, where the stronger lenses are larger. When coupled with the eyepiece lens, the magnification of a microscope ranges from 40X-1000X, though special conditions are required to achieve a sharp image at 1000X magnification.
Why are images observed in a light microscope reversed and inverted?
The lenses used reversed the image.
What are lenses that make objects look larger?
You need a convex lens to magnify an image.
What is the difference in the way light microscopes and electron electron microscopes produce images?
light microscopes allow light to pass through the specimen and use two lenses to form an image. Electron microscopes use beams of electrons, rather than light, to produce images.
How are lenses used in telescopes. Microscopes. And cameras?
They are used to form images of objects. Often they also magnify the image, for example in a telescope or microscope.
What do electrons microscopes use to focus and magnify an image?
Electromagnets focus the electron beam on the specimen. This is a good advantage of electron microscopes over traditional light microscopes where lenses have to be used. Electromagnets can be used as electrons are charged particles and are deflected by magnetic fields.
How does an electron microscope create an image if it will not use light and lenses?
the electrons are used to use to create an image apposed to the light because the beam of electrons has a smaller wavelength than light. This results in electron microscopes having a higher resolving power tham optical (light microscopes) Instead of lenses, the elctron microscopes use magnetic condensors to focus the beam. An image is generated by the electrons hitting a electrosensetive board connected to a computer. Each electron that lands on the board causes a voltage accross the board. The computer then generates an image from many voltages produced by the electrons

What are some ways using convex and concave lenses to form an image that is smaller than the object?
For forming a smaller image than the object using convex and concave lenses, you can place the object closer to the convex lens than its focal length, then position a concave lens closer to the convex lens than the sum of their focal lengths. This arrangement will produce a smaller inverted image. Adjustments can be made by changing the distances between the lenses to fine-tune the size and position of the image.
What are the origins of a microscope?
Microscopes were created by pairing magnifying lenses, so that the image from one could be magnified by the other. The creation of quality glass lenses in the 17th century made possible both the microscope and the telescope, which had been postulated by Roger Bacon in the 13th century.
How do light microscopes defer from electron microscopes?
electron microscopes can help you see very small small organisms. Unlike a light microscope A light microscope uses visible light, focussed by lenses. An electron microscope uses beams of electrons, focussed by magnetic coils. The electron microscope can indeed image smaller objects than an optical (light) microscope. Both can image objects smaller than can be seen with a magnifying glass.
What do microscopes fire at the object to make the picture?
Microscopes typically don't fire anything at objects, they are simply a set of lenses that magnify the image of the object. The lenses bend light to make the object appear bigger. Electron microscopes, however, do fire electrons at objects and construct images out of the return trajectories of the electrons. This is done because electrons don't "wiggle" as much as photons during travel, so they can accurately reflect off of objects smaller than light can. Save
What is the difference between trinocular and binocular microscope?
A monocular microscope has only one eyepiece while a binocular microscope has two eyepieces with different lenses. Binocular microscopes are more popular today than the monocular microscope for professional use. Binocular microscopes have a pair of eyepieces, each with two or more lenses. This allows the operator to use both eyes thus doing away with the eyestrain usually caused by a monocular microscope. Trinocular microscopes or dual-view microscopes on the other hand are microscopes that integrate a digital camera. This allows the operator to views the image on a screen removed from the microscope itself. Trinocular microscopes remove the constraints of the eyepiece and allow the operators to work more comfortably and collaboratively.

How do microscopes differ from electron microscopes?
The microscopes one would think of in a college or high school biology lab are optical microscopes (ie: compound and stereo microscopes) and use light and glass optics in the eyepieces and objective lenses to obtain higher levels of magnification than the human eye can achieve. An electron microscope uses a beam of, you guessed it, electrons to illuminate and produce a magnified image. Electron microscopes are used when the specimens are too small for optical microscopes as they have wavelengths around 100,000 times shorter than visible light and can achieve magnification levels of up to 10,000,000x.
