WebOptical components in an Objective Lens Objective lenses can have just a couple of lens elements, (an achromat and simple lens, for example) or multiple groups of elements. Even two microscope objectives with the same magnification can have a completely different design, as shown in Figure 1. WebA-Plan. This class of objectives provides an attractive alternative to Achroplan objectives, both in routine and research applications. A-Plan objectives provide rich contrast and can be used with eyepieces with a field of view up to 23 mm.They allow contrasting methods ranging from brightfield to phase contrast and for excitation wavelength within the visible …

Nikon has been developing optical technologies since 1917 with the establishment of Nippon … WebOptical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless number. Optical magnification is sometimes referred to as "power" (for example "10× power"), although this can lead to confusion with optical power.
