The microscope magnification depends on both ocular lens and objective lens magnifications. Microscope maginification = Ocular lens magnification × Objective lens magnification You can measure the microscopic field of view on a lower power. 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 Microscope magnification calculation examples: When the ocular lens is 10× and the objective lens is 10×, the field of view is 800 µm. How to calculate the filed of view when the ocular lens is 40× and the objective lens is 100×? Solution: The magnification at lower power is 10 × 10 = 100 The magnification at higher power is 40 × 100 = 4000 higher power field of view = 100 × 800 / 4000 = 20 µm
