Overview of Microscope Magnification
Types of Microscopes
There are several types of microscopes, including compound, stereo, digital, and electron microscopes. Compound microscopes are commonly used in biology and have two sets of lenses that can magnify up to 1000 times. Stereo microscopes are used for examining objects at low magnification, typically up to 100 times. Digital microscopes can magnify up to 200 times and connect to a computer for imaging. Electron microscopes, which use beams of electrons instead of light, can offer the highest magnification power, reaching up to 10 million times.
Magnification Power
The magnification power of microscopes refers to how much larger an object appears when viewed through the lens. Magnification is determined by multiplying the eyepiece magnification by the objective lens magnification. The highest microscope magnification power is achieved using electron microscopes, which can magnify up to 10 million times. However, the highest magnification for light microscopes is around 1000x, limited by the wavelength of the light.
Resolution
Resolution refers to the degree to which detail can be seen in the image produced by the microscope. Higher resolution leads to clearer and more detailed magnified images.
