Field of View (FOV)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, place a transparent metric ruler under the low power (LP) objective of a microscope. Focus the microscope on the scale of the ruler, and measure the diameter of the field of vision in millimeters. Record this number. When you are viewing an object under high power, it is sometimes not possible to determine the field of view directly. The higher the power of magnification, the smaller the field of view.
 The diameter of the field of view under high power can be calculated using the following equation:
For example, if you determine that your field of view is 2.5 mm in diameter using a 10X ocular and 4X objective, you will be able to determine what the field of view will be with the high power objective by using the above formula. For this example, we will designate the high power objective as 40X.
Estimating the Size of the Specimen Under ObservationObjects observed with microscopes are often too small to be measured conveniently in millimeters. Because you are using a scale in millimeters, it is necessary to convert your measurement to micrometers. Remember that 1 μm = 0.001 mm. To estimate the size of an object seen with a microscope, first estimate what fraction of the diameter of the field of vision that the object occupies. Then multiply the diameter you calculated in micrometers by that fraction. For example, if the field of vision’s diameter is 400 μm and the object’s estimated length is about one-tenth of that diameter, multiply the diameter by one-tenth to find the object’s length.
Terms in this set (28) total magnification of both lenses, the objective lens X ocular lens. The ocular eyepiece usually magnifies the image 10X, and the objectives magnify the image 4X, 10X, 40X and 100X. For example, when using the 40X objective and a 10X ocular, the total magnification would be: 4010400. What is the total magnification of an image obtained using a 10X ocular and a 10X objective?The magnification of 100X is achieved by combining the 10X ocular lens with the 10X objective lens. See full answer below. What is the total magnification of an object when using the 10X ocular lens and the high power lens?High Power Objective Lens (40x) The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide. What is the correct magnification of a microscope with a 10X ocular and a 10X objective lens?Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 400). When a 10X objective and a 10X ocular lens are used what is the total magnification of the slide *?The total magnification is the product of the magnifications of two lens systems. Hence, the microscope which has a 10X objective lens and 10X ocular lens, it would magnify the object by 10 xd7 10 100 times What is the field of view of the microscope when using a 10X objective and 10X ocular lens in millimeters?ObjectiveDiameter Of Field Of ViewMagnification (10x Ocular)10×2.0 mm (1.78)100x40x0.4 mm (0.45)400x100x0.2 mm (0.178)1000×1 more row What is the total magnification of a microscope with a 10X * ocular and a 100 * oil immersion objective?1000x What is the total magnification of 10X and 10X?100 times What is the total magnification of a microscope if the ocular lens is 10X and the objective lens is 10X?For example, when using the 40X objective and a 10X ocular, the total magnification would be: 4010400. What is the total magnification If you are using a 10X objective with 10X ocular in place?Answer and Explanation: The magnification of 100X is achieved by combining the 10X ocular lens with the 10X objective lens. What is the total magnification of a 10X ocular lens and a scanner objective lens?100 times What is the total magnification If you use an ocular lens of power 10X and an objective lens of power 4x?Objective lens X Ocular lens Total magnificationFor example:low power:(10X)(10X) 100Xhigh dry:(40X)(10X) 400Xoil immersion:(100X)(10X) 1000X When you are using a 10X ocular and the 10X objective?The total magnification is the product of the magnifications of two lens systems. Hence, the microscope which has a 10X objective lens and 10X ocular lens, it would magnify the object by 10 xd7 10 100 times What is the magnification of a microscope with an ocular lens of 10X and an objective of 100X?100x magnification What is the magnification of the object if the ocular value is 10X and the objective value is 40X?Objective lens X Ocular lens Total magnificationFor example:low power:(10X)(10X) 100Xhigh dry:(40X)(10X) 400Xoil immersion:(100X)(10X) 1000X What will be the total magnification of the ocular lens is 10X and the objective lens is 4X?The total magnification is the product of the magnifications of two lens systems. Hence, the microscope which has a 10X objective lens and 10X ocular lens, it would magnify the object by 10 xd7 10 100 times What is the field of view with a 10X objective?For example, an eyepiece having a magnification of 10x typically has a field number ranging between 16 and 18 millimeters, while a lower magnification eyepiece (5x) has a field number of about 20 millimeters. What is the total magnification when using a 10X objective lens and a 10X ocular lens?The magnification of 100X is achieved by combining the 10X ocular lens with the 10X objective lens. See full answer below. What is the magnification of an object viewed with a 10X objective?The total magnification is the product of the magnifications of two lens systems. Hence, the microscope which has a 10X objective lens and 10X ocular lens, it would magnify the object by 10 xd7 10 100 times What is the total magnification at 10X and 100X?So here The ocular is 10 and the objective is 100. So its 10 times 100 which is 1000. So the total magnification Is 1000 times. Did you know? What is the total magnification of a compound microscope with 10X ocular and 100X objective lens?To calculate the total magnification of the compound light microscope multiply the magnification power of the ocular lens by the power of the objective lens. For instance, a 10x ocular and a 40x objective would have a 400x total magnification. What is the total magnification of a microscope with a 10X ocular and the high power 40X objective in the viewing position?For example, when using the 40X objective and a 10X ocular, the total magnification would be: 4010400. Total magnification is objective eyepiece. What is the total magnification of the eyepiece is 10x and the objective is 10x?The eyepiece in a typical desktop microscope is 10x. The product of the objective magnification and the eyepiece magnification gives the final magnification of the microscope. So, a 60x objective and a 10x eyepiece gives a total magnification of 600x What is the total magnification of a specimen if the ocular lens is 10X and objective lens 40?400x magnification What is the total magnification of a 10X ocular lens and a 10X objective lens?The magnification of 100X is achieved by combining the 10X ocular lens with the 10X objective lens. |
