Q1: Microscope Flashcards
instrument that produces enlarged images of small objects, allowing the observer an exceedingly close view of minute structures at a scale convenient for examination and analysis.
Microscope
Types of Microscopes
- Optical Microscopes
- Electron Microscopes
- Scanning Probe Microscopes
- Stereo Microscope
It creates a magnified image of an object specimen with an objective lens and magnifies the image further more with an eyepiece to allow the user to observe it by the naked eye.
Optical Microscope
Produces a virtual, erect and magnified image from light refraction.
Optical Microscope
Types of optical microscope
- Simple
- Compound
Types of Objective Lenses and thier magnification
- Scanning Objective – 4x
- Low Power Objective – 10x
- High Power Objective – 40x
- Oil Immersion Objective – 100x
Ocular Magnifications
- 5x
- 10x
- 15x
- 20x
Total Magnification Formula
Total Magnification = Eyepiece Magnification x Objective Magnification
defined as the type of microscope in which the source of illumination is the beam of accelerated electrons.
Electron Microscope
It is a special type of microscope with a high resolution of images as the images can be magnified in nanometers.
Electron Microscope
Types of Electron Microscope
- Transmission Electron Microscope (TEM)
- Scanning Electron Microscope (SEM)
A type of microscope with a cantilever sharp enough to move precisely and accurately from a surface of a sample.
Scanning Probe Microscope
Used to study different properties of the sample like electrical properties.
Scanning Probe Microscope
A low-power compound instrument used for a closer examination of three-dimensional specimens than is possible with a hand lens.
Stereo Microscope
Other term for stereo microscope.
Dissecting Microscope
