- For a microscope that has an objective lens magnification of 100X and an ocular lens magnification of 5X, calculate the total magnification. 500X O 1000X O 50X O 100X O No listed answer is correct.Previous question: For example, you can estimate the field of view diameter at 400x total magnification using the measured diameter at 100x total magnification. The magnification is 4 times greater so the field of view will be 4 times smaller. What is the field of view under the 40X objective of the microscope. - The Answer I got for this question was 3/4mm.The compound (bright-field) microscope is parfocal. It means that: Question 4 options: objective lenses are built into revolving nosepiece its lenses effectively decrease focal lenght can achieve maximum resolution lower than 0.2 μm image should remain in focus when objective lens is changed
- 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 ParfocalThe objective lenses of the microscopes used in this course are all parfocal. What does having parfocal objective lenses mean? Question options: The slide has to be moved away from the objective lens (i.e., lowered) when switching between objective lenses. None of these choices The objective lenses have optimized light gathering capability. Once in focus, you may switch between objective lenses with only fine focus adjustment required.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.
- Which of the following is a parameter of microscopy that can affect your ability to resolve a specimen using a compound light microscope? Question options: Contrast Resolving power All of the choices Numerical apertureDifferentiate between the limit of resolution of the typical light microscope and that of the unaided human eyes the relationship between the depth of field and magnification is that When magnification increases, the depth of field decreases. Name two procedures (steps) you should do to achieve the maximum resolution when using the oil immersion lens State the relationship between the working distance of an objective lens and its magnification power “The coarse focus knob can be used to adjust the focus when using any of the objective lenses”. Is this statement true or false? If it is false, please correct it. When using the oil immersion lens but you cannot focus, what should you should not do? And what you should do? What does this statement mean: “Your microscope is parfocal”? What is the significance of condenser lens? Multiple choice question: The most useful adjustment for increasing image contrast in low power magnification is _______ Closing down the diaphragm Closing one…briefly describe the functions of the following parts of the microscope: course objective knob, condenser lens, diaphragm, objective lens, illuminator, fine adjustment knob, oil immersion.
- Complete Table 1 below by supplying the characteristics of each objective. Table 1. Numerical characteristics of microscope objectives. LPO НРО OIO Focal length (mm) Working distance (mm) Linear magnification (X) Numerical aperture (N.A..) Features (color of the band, diameter of the opening of the lens, etc.)Which of these is NOT a best practice when using, handling, or storing a microscope and microscope slides? Do not touch the objective lenses. Store the slides in bright sunlight to prevent mold growth. Rotate the nosepiece to the lowest objective before storing the microscope. Keep dust away from the scope by covering it during storage.Label the parts of the microscope on the diagram below: arm, stage, base, ocular, revolving nosepiece, objective (4x, 10x, 40x), course focus, fine focus, condenser & iris diaphragm (these are marked by the same line)
