1. INTRODUCTION TO MICROSCOPY A microscope is an instrument used to see objects that are very small for the naked eye. The science of examining small objects using such a tool is called microscopy. Microscopic means invisible to the eye except aided by a microscope. 2.
How does the microscope work? How does it use light? Optical microscope: a microscope that uses visible light in order to create images. The optical or light microscope consists of different parts (as you see in the picture), and each piece have a different name. The eyepiece lens consists of one lens, and that’s where you look through.
This is done through the use of curved lenses and an electronic eye. This telescopes allows astronomers to be able to produce images of the celestial bodies so that further study can be completed. As time goes on, the X-ray images of stars from the telescopes give astronomers a lot of information such as the patterns and changes that may be occurring. X-rays are a form of radiation just like heat or light. They are invisible to the human eye but easily absorbed, however an X-ray telescope does not allow the X-rays to be absorbed.
The Detector: The separated ions are then measured, and the results displayed on a chart. Mass spectrometry has both qualitative and quantitative uses. These include determining the structure of a compound, quantifying the amount of a compound in a sample and determining the isotopic composition of elements in a molecule. This technique basically studies the effect of ionizing energy on molecules. It depends upon chemical reactions in the gas phase in which sample molecules are consumed during the formation of ionic and neutral species.
When light passes through the subject and pass to the observer to the location when camera is placed. If the light goes through a little opening, it can create a picture on the opposite side of the opening. In the SLR camera, when the shutter is closed, no light will be passing through the sensor, so the photographers must get viewfinder to view the subject. This will lead to a slight difference view of the image. The DSLR sensors are made of millions of photo sites.
The objective lens has a larger focal length than the eyepiece lens because the objective lens must collect light from a distant object and then refract and ‘channel’ it to the eyepiece end of the telescope. The eyepiece lens, on the other hand, doesn’t need to have a large diameter or focal length because its job isn’t to collect light, but to magnify the image formed by the objective lens. This means the length of a telescope from one lens to the other is approximately the sum of the focal lengths of the two
larger field depth allows the screen to be located at any difference from the projector. COMBINER: A special mirror known as a combiner or beam splitter is required for both reflection and transmission .silvered half of mirror reflects the light while the other transparent half transmits light.the combiner must be properly positioned to view the image processed by the computer.the cloak and the background image must be fully integrated for realistic
Mass spectrometry detectors are possibly the best for selectivity. It works with the positive ion, a positive ion is achieved by knocking off two or more electrons of the atom or molecule (The mass spectrometer - how it works, no date.) To have the same kinetic energy the positive ions are accelerated. The magnetic field deflects the ions according to their masses. The deflection depends on how many electrons were removed in the first stage.
Therefore if the focal length is longer the image will be larger. How bright an image will be also depends on how much light is collected by the telescope. The area of the objective lense is
