To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. To determine the total magnification of an image viewed through a microscope, multiply the power of the eyepiece or ocular lens by the power of the objective lens. A reference chart is given below which shows video magnification for various monitor and chip sizes. Therefore, the total magnification is 40x. Multiply the magnification of the lenses together. The total magnification of 40 means that the object appears forty times larger than the actual object. The video magnification is determined by dividing the TV monitor diagonal (mm) by the CCD chip diagonal (mm). In the above example, if the measured length of a specimen was 100 mm, the A reference chart is given below which shows video magnification for various monitor and chip sizes. Total Magnification Equal to the power of the ocular lens multiplied by the power of the objective lens being used magnifies 45x, total magnification is 450x (10 x 45). If the magnification power of the ocular lens is 10x and that of the objective lens is 4x, total magnification is 40x. The formula used to calculate total magnification on the TV monitor is: Total Magnification = Objective Magnification x Microscope Adapter Magnification x Video Magnification. The telescope’s focal length (for example, 1200mm) 2. In order to determine the total Total Magnification: To figure the total magnification of an image that you are viewing through the microscope is really quite simple. Then the field of view of higher power can be calculated based on following formula: Low power magnification × Low Power field of view = high power magnification × high power field of view For example, if the eyepiece magnification is 10x and the objective lens in use has a magnification of 4x, the total magnification is 10 × 4 = 40. Most compound microscopes have a 10x eyepiece and three objectives, 4x, 10x and 40x. image diagonal (as measured on the screen) by the CCD chip diagonal. Changing Magnification and Measurement real size of the specimen would be: SPOT Imaging builds life science imaging focused on productive workflow. Calculating Magnification Once the magnification of each individual lens is known, calculating total magnification is simple math. To determine “Video Magnification” on a computer monitor divide the actual This article describes how to calculate the effective magnification and the size of your sample on your monitor when using a digital camera on a microscope. To get started, we just need two numbers: 1. We achieve this by creating intuitive work environments that leverage proven technology with outstanding support. What is the magnification on the TV monitor when using a 10X objective, 0.45x video coupler, a 1/2″ format CCD and a 19″ monitor? The eyepiece’s focal length (for example, 25mm) To find the magnification, we’ll simply divide the numbers: 1200mm / 25mm = 48x magnification That’s it! The approximate real size of a specimen can be determined by dividing the length of the specimen measured on the monitor screen by the total magnification on the monitor. If we wanted more magnification, we could use an eyepiece with a shorter focal length, such as 10mm: 1200mm/10mm = 120x magnification We could also use these eyepieces with a … If the eyepiece magnification of a microscope is 10x and the objective lens in use has a magnification of 4x, calculate the magnification of the microscope. Microscope maginification = Ocular lens magnification × Objective lens magnification You can measure the microscopic field of view on a lower power. Then divide 18 by 400 to get an FOV diameter of 0.045 millimeters. magnification on the TV monitor, the following variables must be known: The formula used to calculate total magnification on the TV monitor is: Total Magnification = Objective Magnification x Microscope Adapter Magnification x Video Magnification. Magnification = scale bar image divided by actual scale bar length (written on the scale bar). (Click Here To See Image) (Click Here To See Image) (Click Here To See Image) For example, if the eyepiece reads 10x/18, and the magnification of your objective lens is 40, multiply 10 and 40 to get 400. The video magnification is determined by dividing the TV monitor diagonal (mm) by the CCD chip diagonal (mm). Electron microscopes
