WebJun 7, 2024 · Divide the field number by the magnification number. For instance, if the eyepiece is labeled as 30x/18, then 18 ÷ 30 = 0.6, meaning that the diameter of for is 0.6 millimeters. For microscopes that only have an eyepiece, this will be enough. But having an objective lens as well makes the calculation harder. WebSep 12, 2024 · The focal length f of the magnifying lens may be calculated by solving Equation 2.8.8 for f, which gives M = 1 + 25cm f f = 25cm M − 1 = 25cm 5.0 − 1 = 6.3cm b. To get an image magnified by a factor of ten, we again solve Equation 2.8.8 for f, but this time we use M = 10. The result is f = 25cm M − 1 = 25cm 10 − 1 = 2.8cm. Significance
WebConsider our example of a 10mm diameter 4MHz probe pulsed into water. The standard equation = ˝ ˛ ˚ predicts a near field distance of 67mm. The Civa model using water at 1483m/s will provide a near field in water of about 67mm for a probe with a 50% bandwidth. This is seen in Figure 5 and compares well with the value derived from the simple ...
