WebThe 40x magnification is longer than the 10x magnification. Because of this, only the fine focus knob should be used with the 40x lens, so that it does not get scratched by slides. The eyepiece of the microscope contains a 10x magnifying lens, so the 10x objective lens actually magnifies 100 times and the 40x objective lens magnifies 400 times.
