the place Focal Size is the measurement taken utilizing the focal size gauge. To calculate the magnification of the lens, we will use the next formulation:
Magnification = Lens Energy (in diopters) x 4 (since most goal lenses have a focal size of 4 mm)
Instance of Calculating Lens Energy and Magnification
| Goal Lens | Focal Size (mm) | Lens Energy (dipters) | Magnification |
| — | — | — | — |
| Goal Lens 1 | 4.0 | 0.25 | 1x |
| Goal Lens 2 | 12.5 | 0.08 | 3.2x |
| Goal Lens 3 | 16.0 | 0.0625 | 2.5x |
To calculate the magnification of every lens, we used the formulation: Magnification = Lens Energy (in diopters) x 4. The calculated magnification values are proven within the desk.
On this instance, the magnification of Goal Lens 1 is 1x, the magnification of Goal Lens 2 is 3.2x, and the magnification of Goal Lens 3 is 2.5x. These values can be utilized to calculate the whole magnification of the microscope, which will probably be mentioned within the subsequent part.
