- What is the diameter of the field of view (DFV) of a 1000x objective lens if the DFV of a 400x objective lens is 500 μ? Express your answer in mm.Using the Field of View (FoV) formula (Low Magnification/High Magnification)= (High Field of View/Low Field of View) determine the FoV in microns for all other objective lenses listed in yourtable given that the diameter of the 4X scanner FoV is 3.2 mmTo obtain a 400X magnification image you may choose a 40X objective lens with a 10X projector lens, or a 20X objective lens with a 20X projector lens. What are the differences in their image quality?
- A michroscope has a 20x ocular and two objectives of 10x and 43x respectively: calculate the apparent magnification for low and high power lenses.If the ocular lens is 10x, what would be the total magnification for the following objectives lenses? 5x 17x 35xWhat is the total magnification of a specimen viewed with a 10x ocular lens and a 45x objective lens? O 45x O 100x 4.5x O 450x O 10x
- If the total magnification is 2000X with the use of a 10X ocular lens, what is the magnification of the objective lens? 1 017If you have chosen the objective lens with 10x and the ocular lens magnification is also 10x. Then the total magnification will be 100x. True FalseIf the total magnification of a slide is 400x and the ocular lenses are 10x, what is the magnifying power of the objective being used?
- How does the numerical aperture of an objective lens affect resolution? Question options: Numerical aperture is the optical plane visible for each objective lens Numerical aperture decreases the amount of excess light on a specimen increasing the resolution and clarity Numerical aperture is the loss of light due to changes in density between the specimen and the objective lens Numerical aperture is a measure of the amount of light an objective lens can accept producing higher resolution and allowing smaller structures to be visualized with greater clarityUsing the Field of View (FoV) formula: (Low Magnification/High Magnification)= (High Field of View/Low Field of View) determine the FoV in microns for all other objective lenses (4x,10x,40,100x) given that the diameter of the 4X scanner FoV is 3.2 mm Please, explain with the formula how it was used and how values were addedIn this image a stage micrometer and an ocular micrometer are aligned so that the 10 o.u. line aligns with the 100um line.
