They Use Electrons to Form An Image
These microscopes use electrons to form an image - there are two types of electron microscopes, we will cover that later!
- It's unlikely you'll have used these before - they range from £60,000 to £10,000,000 depending on the type and the equipment.
- Very few schools have this type of microscope, but a lot of universities have them though.
A Higher Resolution
They have a higher resolution than optical microscopes, with a maximum resolution of around 0.0002μm.
- They also have a higher magnification of about 500,000 times - a lot higher than an optical microscope!
- However, electron microscopes only produce black and white images, but they can be coloured with a computer!
