    A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…

    Introduction A lens is an object that forms images by refracting light. The images formed can be magnified, real and virtual depending on what lens used and the set-up of the lens system. There are two types of lenses, converging and diverging lenses. Converging lenses cause parallel light rays to converge to a point. Diverging lenses cause parallel light rays to diverge. Typically converging lens are thicker in the middle and diverging lenses are thinner in the middle. Lenses are used for many…

    When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

    scientists have created a type of bionic lens that allow humans to zero in on the tiniest of objects without the assistance of a third item such as the microscope. For hundreds of years, scientists have been using the microscopes to make major discoveries such as proving the existence of minuscule living organisms that cannot be seen to the naked eye. However due to the physical laws restricting light to pass through conventional lens to see these small items, we had begun to be dependent on…

    The part of the image that is seen through the lens is in focus while everything outside of the lens frame is out of focus. The human eye is a fascinating organ. There are many parts of the eye that aid in allowing a person to see, but this paper will talk only the components that allow images to form on the retina. In general, the ciliary muscle can relax or contract to adjust the focal length of the lens. When the muscle is contracted, the curvature of the lens increases, thereby decreasing…
