How does magnification workon a microscope

The higher the magnification power of a lens, the more important the positioning of the object will be in order to see it sharply. The object will go in and out of focus quickly on a high power lens versus a weaker lens. The user has to be more accurate in positioning the object under the lens.

The field of view decreases as the dioptre or magnification increases. A higher magnification lens makes smaller details look bigger, however, less of the total object is in focus because the field of view is reduced. When choosing a magnifier, there is a trade-off between the field of view and the amount of magnification required.

For example, to calculate the magnification (power) of a 3 dioptres lens: 3 dioptres divided by 4 = 0.75 + 1 = 1.75X (the original object appears 75% bigger) 5 dioptres divided by 4 = 1.25 + 1 = 2.25X (the original object appears 125% bigger) 12 dioptres divided by 4 = 3.0 + 1 = 4.00X (the original object appears 300% bigger)

A 3 dioptres (1.75X) lens is the most popular standard magnification lens because it offers good magnification and ease of use.

These two terms come up frequently on product pages, for example across our range of magnifying lamps. Dioptre refers to the curvature of the lens. As the dioptre increases, the lens become thicker and the curvature greater. As the curvature increases, light rays are redirected to fill a greater portion of the viewer’s retina which makes the object look bigger. Power (magnification) refers to how much larger an object is made to look through a magnifying lens. Power is typically indicated by an X such 2X or 4X. Daylight uses the most common formula to calculate power: dioptre / 4 + 1

What is focal length? The focal length is the optimal focus point from the centre of a lens to the magnified object. It is the distance at which the object is at its sharpest. The focal length is measured in millimetres (mm).
