- When focusing a light microscope, why is it best to adjust the focus using the coarse focusing knob before using the fine focusing knob?An object found with the 10x objective of the microscope may be viewed with the 40x objective without having to re-focus. This property of the microscope is called: O Confocal O Bifocal Binocular d ParfocalExplain when to use bright-field, phase-contrast, dark-field, fluorescence, transmission electron, and scanning electron microscopy for a given situation. What is an example of this situation?
- Within the microscope image below, identify the type of microscopy used by dragging the correct label to the target in the image. A Electron 10 μm Q microscope B Fluorescence microscopeWhat description best describes the compound light microscope? Uses a beam of electrons is transmitted through a specimen to form an image. Has more than one lens and its own light source. In this type of microscope, there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. An optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. Designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it.For each type of microscopy, know how each is used and the type of image produced. kEEP IT SHORT AND SWEET Light microscope – Transmission electron microscope - Scanning electron microscope –
