- Explain why both magnification and resolution are important in order to see a microscopic organism?Which of the following is true about the relationship between depth of field and magnification? There is no relationship. When magnification increases, depth of field decreases. When magnification increases, depth of field increases. Stereomicroscopes offer a lesser depth of field than compound microscopes. The depth of field of a microscope determines how much magnification it can achieve.What 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.
- What are microscopes? Make a brief outline of the history of microscopes? Relate microscopy with our present status in the scientific and economic world. What are wet mounts? How to prepare wet mounts? How to remove water bubbles in wet mounts? What are the steps in manipulating / focusing the microscope? What are the reminders before storing the microscope? How many times an object is enlarged when a) HPO is used LPO is used Oil immersion objective a. when to use the coarse adjustment knob? when to use the fine adjustment knob if given the chance to manipulate the microscope, what particular specimen would you like to see first . Why ? Conclusion : state your conclusionDo you consider the microscope as the best representation of a medical technologist? Why or why not? Explain your answer.If you were trying to visualize living organisms without staining, which type of microscopy would be best to utilize? O 1) brightfield O 2) TEM 3) fluorescent O 4) confocal O 5) phase contrast
- PRELAB: Calculating Magnification Each lens makes the object look larger by a specified amount. To determine the total magnification, multiply the magnification of the eyepiece and the objective being used. Table 1: Microscope Magnification Magnifying power Objective Objective Eyepiece Total name Scanner 4 X Low power 100 X High power 40 χ PRELAB: Estimating the Size of an Object using a Microscope You will not be able to use a ruler to directly measure the size of a cell. Instead, you will use an indirect method by comparing the cell to the size of something you already know. The diameter of the microscope's field of view as seen through the eyepiece is a convenient length to use. A very small unit of measurement, the micron (µm) is used for measuring microscopic objects. The conversions are: 1 um = 0.001 mm 1 mm = 1000 µm Table 2: Field of View Diameters Objective Diameter name millimeter (mm) micron (um) Scanner 4 Low power High power 0.5 To estimate the size of an object, divide…Do you consider the microscope as the best representation of a medical technologist? Why or why not?Define the terms magnification and resolution.
- The following questions talk about increasing magnification in microscopes. Please answer questions 1 and 2 After a specimen is in focus, where in the field of view should position the specimen before increasing the magnification (be precise)? (QUESTION 2 HAS TWO PARTS TO IT): To increase the magnification, which objective should you click into position next? After refocusing the specimen with the new objective, if you want to increase the magnification even more, which objective should you now click into position?make a comparison viewing a microscope slide under low magnification and high magnification by identifying benefits and drawbacks for each.Put the steps for using a microscope in order. While looking through the eyepiece, use the coarse adjustment knob to bring the object roughly into focus. Lower the stage as far away from the objectives as possible. Use the fine adjustment knob to bring the object into sharp focus. Turn on the light. Place the slide on the stage and center it. Turn the nosepiece to the lowest power objective.
