Low power magnification formula
WebIn Equation 1 , m is magnification. Figure 1: The components of a compound microscope. (1)mSystem = mObjective× mEyepiece m System = m Objective × m Eyepiece Eyepieces When microscopes were first invented, eyepieces played a major role in their design since they were the only means to actually see the object under inspection. WebMaximum useful magnification is reached with an eyepiece exit pupil of 0.7 mm - 0.8 mm. It is not a precisely defined limit, more a guide for optimum magnification. · Mopt = aperture in mm / 0.7; A telescope with an aperture of 100 mm would therefore have a optimum magnification of 142-times and a 200 mm telescope of 285-times.
