WebFor a low magnification objective such as a 4X or even a 10X, the typical depth of field is plus or minus 3 to 5 microns. In that case, if the sample is very flat, focusing may not be required at all, or only one needs to happen one time. Generally speaking, samples vary in thickness and they vary in flatness, so focusing is required. WebTo calculate the diameter of the field of view for low (40X) and medium (100 X) power. 1. Calculate the total magnification of the low power objective lens by multiplying the magnification of the ocular lens by the magnification of the objective lens. The magnification of the lenses is etched on the sides of the actual lens holders.

How to calculate the low power magnification

Web23 jan. 2024 · To calculate the diopter, we’re going to have to multiply that magnification by four, and here’s why: When a 1d lens (1 diopter) bends light, the size of the object being viewed increases by 0.25. So if we had a 4d lens, the size of our object would increase by 100 percent. Hence, a magnification of 1x. WebNow we just need to use some algebra and solve for “FOVhigh”. 0.8 * 100 = FOVhigh * 400. 80/400 = FOVhigh. 0.2 = FOVhigh 0.2 millimeters or 200 micrometers is the diameter for the field of view for the 40X objective under 400X magnification in this example.
