Introduction

Setting up a Light Microscope

Aim: To set up a Light Microscope

Microscopes came into existence in 1670. It was a man called Antoni Van Leeuwenhoek who came up with this innovative idea of inventing a Microscope. Soon his invention was very popular. Scientists everywhere started to utilize similar microscopes. Microscopes have been an asset to the scientific industry. We nowadays use microscopes to things in a greater detailed picture. The naked eye cannot see an onion cell, to observe the onion cell we need to use a Light Microscope. When using a Light Microscope we can adjust the magnification to what we desire. A light microscope is an excellent piece of equipment to use when distinguishing between an animal and plant cell. image00.pngimage01.png

There are many types of microscopes. Two common microscopes are the Light Microscope and the Electron Microscope.

Method  

You have to be very careful when using a light microscope. Follow these i9nstructions to setup and use the microscope properly.

  • First of all place the microscope in the middle of the table and close to the lamp that will supply the light for you to see the slide clearly. Make sure the hand grip of the microscope is pointing towards you. If the microscope you are using has more than one objective lens, start with one with the lowest number.
  • Once the microscope is set, look down it. Adjust the magnification until you can see a plain bright screen.
  • After you have set the magnification, then put the slide that you are studying on to the stage of the microscope.
  • Now again look down the microscope. Slowly turn the focusing knob so that the objective lens is moving away from the slide. Then you can slowly focus the slide up to the magnifications you desire.

Conclusion

Microscopes have answered some of the questions that the naked eye cannot see. For example the naked eye cannot see an onion cell, to see the onion cell we have to use a microscope.

Evaluation

I think setting up a light microscope is very simple and easy. The advantage of a microscope is that you can set it up very fast and get to work straight away. You don’t need any special training to use a microscope, it is basically common sense. A disadvantage is that it can be moved easily by some one walking past and nudging it out of position. And when that happens you have to refocus and reposition the microscope. The solution to this problem is that lamps should be fitted on the microscopes. However I think that the microscope is a brilliant piece of equipment.

    Electron microscope also helps us to see deep into the specimen and view the organells. Scientists have taken advantage over this by breaking up cells to get organells and find their functions and properties. Explanation of the terms magnification and resolution.

  2. My experiments focus is to obtain an accurate measurement for a specific lenss power.

    They intercept the x axis at -6.26 D, -6.38D and -6.46 D respectively. The average of these results turns out to be 6.37 D with an uncertainty of +/- 0.1.

    It was viewed with a microscope with low and then high power. Results Evaluation Peeling the onion skin was the easy part but looking at the microscope was hard because the onion was thin and it kept folding over.

    These are observed in a Scanning Electron Microscope. Electron microscopes can, when pushed to their boundaries, view objects as small as the diameter of an atom. It can magnify up to 1 million times, but electron microscopes have a severe drawback, which is that no living specimen can survive under their high vacuum.

    * Viewing with a microscope I looked at the slide through low power then followed by high. Evaluation: I could see less detail in the lower magnification and in the high magnification I could see more detail such as the cytoplasm.

  2. The eye.

    Some mammals have a reflective layer called the tapetum in retina e.g. common nocturnal mammals - means light entering eye stimulates retina cells twice - increases sensitivity at low intensities. Blind spot - where neurons project through retina into optic nerve, no photoreceptors.

  1. Optical and Electron Microscopy

    There are two types of electron microscopy, transmission electron microscopy and scanning electron microscopy. Transmission Electron Microscopy: (TEM) In a transmission electron microscope, a high voltage is applied to a heated tungsten filament, which as a result generates electrons. To accelerate the electrons, a high negative voltage is applied to

  2. History of the Microscope

    Today, the term "microscope" is generally used to refer to this type of compound microscope. In the compound microscope, the lens closer to the object to be viewed is refers to as the "objective", while the lens closer to the eye is called the "eyepiece".
