Q. = ocular x objective For example, if the ocular is 10x and the low power objective is 20x, then the total magnification under low power is 10 x 20 = 200x. total mag. Use the SCANNING (4x) objective and course focus adjustment to focus, then move the 100X– This objective magnifies the image by a factor of 100. Field of view is how much of your specimen or object you will be able to see through the microscope. Total magnification: In a compound microscope the total magnification is the product of the objective and ocular lenses (see figure below). These include:low magnification objectives (5x and 10x) intermediate magnification objectives(20x and 50x) and high magnification objectives (100x). Almost any feature you need to observe in this course can be located with the 100X total magnification this objective provides. revolving nosepiece. What is the total magnification with each ojective? In addition to the objective lenses, the ocular lens (eyepiece) has a magnification. A: (low power ) _____ A: (high power ) _____ Q: If you are looking through a Thus the total mag. medium objective lens. The magnification of a microscope can be calculated by multiplying the power of the objective lens with an ocular or eyepiece lens. To calculate the total magnification of a compound microscope, you multiply the eyepiece magnification and the objective (lens) magnification. 5. Calculate the low power magnification of this microscope. Always start with the stage as low as possible and using scanning objective (4x). what is the total magnification of the lowest power of objective lens? It gives the observer an overview of the entire slide. The objective lenses are also color coded. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. The same principle apply to stereo microscopes, a 10X eye piece combined with a 4X objective lens will produce 40X magnification. The. Magnification. high objective lens. 6. You multiply the power of the ocular and the power of the objective being used. = ocular x objective For example, if the ocular is 10x and the low power objective is 20x, then the total magnification under low power is 10 x 20 = 200x. Usually, the ocular lens has a magnification of 10x. The high-dry power objective lens is 40x. 10x5=50. At 1000x magnification you will be able to see these same items, but you will be able to see them even closer up. Low Power Objective (10X): This next shortest objective is probably the most useful lens for viewing slides. The total magnification will … OBJECTIVE LENS OBJECTIVE POWER OCULAR POWER TOTAL MAGNIFICATION Scanning 4x 10x 40x Low power 10x 10x 100x High Power 40x 10x 400x Oil Immersion 100x 10x 1000x For example, if you use the high power objective lens to look at a human cell that is 50 µm in diameter, it will look 20 mm in diameter through the microscope (50 µm x 400 = 20,000 µm = 20 mm). Q. 9. For each objective on your microscope, calculate what the total magnification of a specimen would be when viewed under that objective. 43X (or 45X)– This objective magnifies the image by a factor of 43 (or 45) and is referred to as the “high power” objective. 300 seconds . Essentially, objective lenses can be categorizedin to three main categories based on their magnification power. Remember, the magnifying factor is a whole number, and differs for each different objective.
