When you use this device, it is suggested for you to spare the time for preparing the microscope. You should also centralize this device appropriately. If you have done the steps appropriately, then looking at the specimen under this device can be a wonderful experience.

Before using it, you should ensure that it is plugged in. If it has an external light source, you can turn it on. Then, you can prepare the sample to be examined.

To examine the sample, you should ensure that the scanning objective lens is in its place. Position the slide or specimen under the microscope. For security of the slides, you can use the stage clips.

Then, for bringing the specimen into focus, you can use the coarse adjustment knob. Do not forget to centralize the specimen in the vision field. Again, use the coarse adjustment that is followed by the fine adjustment, so you can focus to see the sample. You can adjust the source of light if necessary.

To make the slide accessible easily, you can rotate the low power of objective lens. Then, place a small drop of oil directly on the slide over the sample.

To bring the specimen into focus, you should only use the fine adjustment. Utilizing the coarse adjustment knob can result in damaging the lens or the slide. If you have finished, before removing the slide, you should make sure to rotate the scanning objective lens into place. In the end, clean the lenses if necessary and turn off the power supply.

Parts of a Microscope

The microscope was invented by two Dutch eyeglass makers named Zacharias Jansen and his father Hans in the year 1590. They put several lenses in to a tube and found out that it can enlarge an object by as much as 9 times its normal size and the images were not so clear. The first microscopes were used more as a novelty item rather than a scientific instrument. Galileo Galilei heard of this new invention and made a better microscope. In the late 1600's, Anthony Van Leeunhoek made use of a real microscope. His microscope had a magnification of 270 times, which during those times other microscopes can only achieve 50 times of magnification. This led to many scientific discoveries and people started seeing things in places where they seem to be empty.

Parts of a Microscope:

 

• Eyepiece lens - It is the lens where we look through, its magnification is usually 10-15 times.
• Tube - This connects the objective lens and the eyepiece.
• Arm - It gives support to the tube and connects it to the base.
• Base - It supports the whole microscope and is located at the bottom.
• Mirror - Used to reflect light from an external light source to the bottom of the stage. This is used to give light to the specimen on the stage.
• Stage - It is where the slides are placed. The stage has clips to hold the slide in place, it has adjustable knobs that move the platform left and right; and up and down.
• Turret or the Revolving Nosepiece - Two or more objective lenses are in this part. These objective lenses can be rotated to change power.
• Objective lenses - There are usually three objective lenses on a microscope. The shortest lens has the lowest magnifying power and the longest one has the highest magnifying power. The longest lens is retractable because it has a spring in it in order to protect it from hitting the slide.
• Rack Stop - The rack stop keeps users from breaking the lens or slide by preventing them to adjust the lens too low. Factories set this and should only be adjusted when using very thin slides.
• Condenser Lens - Condenser lenses focus light to the specimen making images sharper. They are more useful at the highest powers.
• Diaphragm or Iris - The diaphragm is used to vary the intensity and size of the light that is focused to the slide.

A Camera’s Lens Isn’t Its Most Important Part
Photographers are notoriously cranky and opinionated online. Even they’ll admit that. I wonder why that is? Maybe it’s because photography is something of a black art.
