WebMagnification in a microscope refers to the amount or degree of visual enlargement of an observed object. Magnification is measured by multiples, such as 2X, 4X, and 10X, indicating that the object is enlarged to twice as big, … Web(Note: N.A. is only important with high power microscopes). Objective Lens: The lens closest to the object. In a stereo (low power) microscope there are objective pairs, one lens for each eyepiece lens. This gives the 3-D effect. On a stereo microscope the objective lens is built into the body of the microscope and can not be changed.

WebA stereo (or low power microscope) may also have two eyepieces, but since each eyepiece views through a separate objective lens, the specimen appears in stereo (3-Dimensional). In order to distinguish from monocular or trinocular microscopes, we have included both types of binocular microscopes in our Binocular Microscope category. WebThe numerical aperture of a microscope objective is the measure of its ability to gather light and to resolve fine specimen detail while working at a fixed object (or specimen) distance. Image-forming light waves pass through the specimen and enter the objective in an inverted cone as illustrated in Figure 1 (a).
