What is the advantages and disadvantages of a light microscope?
Advantage: Light microscopes have high magnification. Electron microscopes are helpful in viewing surface details of a specimen. Disadvantage: Light microscopes can be used only in the presence of light and have lower resolution. Electron microscopes can be used only for viewing ultra-thin specimens.
What are the advantages of a light microscope over an electron?
Resolution: The biggest advantage is that they have a higher resolution and are therefore also able of a higher magnification (up to 2 million times). Light microscopes can show a useful magnification only up to 1000-2000 times. This is a physical limit imposed by the wavelength of the light.
What are the disadvantages of a compound light microscope?
Cons:
- The magnifying power of a compound light microscope is limited to 2000 times.
- Certain specimens, such as viruses, atoms, and molecules can’t be viewed with it.
What are 2 advantages of light microscopes?
Advantages
- Inexpensive to buy and operate.
- Relatively small.
- Both living and dead specimens can be viewed.
- Little expertise is required in order to set up and use the microscope.
- The original colour of the specimen can be viewed.
What is the disadvantages of microscope?
The main disadvantages are cost, size, maintenance, researcher training and image artifacts resulting from specimen preparation. This type of microscope is a large, cumbersome, expensive piece of equipment, extremely sensitive to vibration and external magnetic fields.
What is the cost of a compound light microscope?
| Microscope | Brand | Price |

| 40X-2500X LED Digital Binocular Compound Microscope w 3D Stage + 5MP USB Camera | AmScope | $310.99 |
| OMAX 40X-2500X LED BINOCULAR LAB COMPOUND MICROSCOPE WITH 5MP CAMERA AND MECHANICAL STAGE | OMAX | $313.99 |
| Labomed 9135010 CxL Binocular Cordless Microscope, 4x, 10x, 40x Objectives, LED Illumination | Labomed | $611.80 |
What can be viewed with a compound light microscope?
With higher levels of magnification than stereo microscopes, a compound microscope uses a compound lens to view specimens which cannot be seen at lower magnification, such as cell structures, blood, or water organisms.
What are the characteristics of a compound light microscope?
Compound light microscopes are commonly used to view items that are too small to see with the naked eye. They have several strengths of objective lenses and rely on light shining from beneath the specimen. This requires that a specimen be very thin and at least partly translucent.
What is the magnification of a compound microscope?
Compound microscopes typically provide magnification in the range of 40x-1000x, while a stereo microscope will provide magnification of 10x-40x. Compound microscopes are used to view small samples that can not be identified with the naked eye.
What are light and electron microscopes?
Light microscopes (optical microscopes) and electron microscopes are both used to look at very small objects. The main difference between light microscope and electron microscope is that light microscopes use beams of light to illuminate the object under examination while the electron microscope uses beams of electrons to illuminate the object.
