- These cells are being viewed under high power. Use the length of just one cell to estimate the number of cells that can fit into the FOV. Scanning power objective = 5X; Low power objective = 40X; High power objective = 100X; Eyepiece = 10X; Low power field of view (FOV) = 1.5 mmPART C: CALCULATING THE DIAMETER OF THE FIELD OF VIEW (FOV)_ The field of view (FOV) is the circular area you can see when you look through the microscope. The diameter of the field of view is different depending on which objective lens you are using. For example, you are using the medium-power objective lens, then the area you can see is actually smaller than if you were using the low-power objective lens. Knowing The diameter of the field of view can help you estimate actual size of objects / cells seen through the microscope. When the revolving nose piece is turned to the low power objective lens, a dear plastic ruler can be placed on the microscope stage (see figure 1). Then, the coarse adjustment knob can be used to focus on the millimeter marks of the ruler making sure that one of the milimeter marks is at the left edge of the field of view (see figure 2). NOTE: Slage cip I-1000 Objects in the FOV are usually measured in micrometers (um). To convert, a FOV in mm, times it by 1000…Previous question: The field of view is the maximum area visible through the lenses of a microscope, and it is represented by a diameter. To determine the diameter of your field of view, you can place a transparent metric ruler under the low power (10X) objective of a microscope. You would focus the microscope on the scale of the ruler and measure the diameter of the field of vision in millimeters. Refer to the image taken of this preparation below. What is the approximate field of view as seen by this 10X objective. Note: This microscope has a 10X eyepiece, giving a total magnification of 100X. The image shows the 1mm is for this question. - Answer for this question was 3mm.

Use the table below to determine the size of this cell. 1 ocular unit = Objective lens 25 um 4 x 10 μη 10 x 2.5 um 40 x 100 x 1 µmUsing the scanning (4x) objective and the metric ruler, record the number of millimeters you see along with the letter “e.” Your value: 2 millimeters Convert the figure you attained to micrometers (1 millimeter = 1,000 micrometers). This is the diameter of the field of view for the low-power objective (LPD). The field of view is the circular field you see when you look through the oculars. The field of view changes at different magnifications.
