Magnification is a significant factor in an optical microscope’s performance. What does magnification mean exactly? The ratio between the size of a particular feature of an item or sample as shown in an image created by an optical system and the actual size of the feature on the object itself is a simple definition of magnification. A microscope’s ability to produce a picture of an object at a scale that is larger (or even smaller) than its real size is known as magnification.

Only when it is feasible to discern more details of an object in the image than when observing the object with the unaided eye can magnification serve a beneficial purpose. Magnification is currently clearly visible while looking at an image of a sample through a microscope’s eyepieces. There are recorded strict international norms for this situation. While many of these guidelines also apply to digital microscopy, where the image is frequently viewed on an electronic monitor, strict definitions and guidelines for the magnification achieved by a digital microscope have just recently been established.

NextGen’s Universal Hardness Tester for Vickers / Knoop, Rockwell and Brinell has the following magnification: Eyepiece: 15X, 2.5X (for Brinell), 5X (for Vickers) (10X, 20X for optional)

Total magnification: 37.5X, 75X.
