Magnification value in pharmacology

New Magnification value in pharmacology. Many patients with subnormal vision who have been relegated to a nonvisual life can be rehabilitated with proper magnifying devices. While most of these devices are applicable to near-vision problems only, some are useful for distance functions. There is nothing new or mysterious about the principles and application of magnification in the problem of low vision.

Magnification is the process of enlarging the apparent size , not physical size, of something. This enlargement is quantified by a size ratio called optical magnification. When this number is less than one, it refers to a reduction in size, sometimes called de-magnification. Typically, magnification is related to scaling up visuals or images to be able to see more detail, increasing resolution , using microscope , printing techniques, or digital processing. In all cases, the magnification of the image does not change the perspective of the image. Some optical instruments provide visual aid by magnifying small or distant subjects.

Magnification refers to an action of magnifying something. Furthermore, it refers to enlarging the apparent size and not the physical size. This enlargement is certainly quantifiable. Furthermore, how an object magnifies in relation to its actual size, is an important discussion under magnification. In this topic, we will discuss this concept and how it helps to magnify objects. It refers to the action of visually enlarging an object with the help of lenses. Also, the object does not physically become larger but only appear larger. Besides, this concept ascends from two forms. First is by microscope that make small objects appear large and second is by telescope that makes a distant object appear closer and the images are more clear and defined. Besides, both these tools and forms utilize two different formulas and tools. Also, microscopic magnification helps us to study the structure and composition of objects. While on the other hand, telescopic magnifies the object such as stars, planets, etc. It refers to a simple lens that we use to magnify an object.

One important criterion concerning optical microscope performance is magnification. This article offers helpful guidelines for digital microscopy, so users can determine the useful range of magnification values. For more than years, optical microscopy has allowed the observation of microscopic entities not seen by the unaided eye [1]. Today there are many types, but here the focus will be on digital microscopes [2] with electronic image sensors, but no eyepieces, and stereo microscopes [3,4] with eyepieces. Additionally, a stereo microscope can be equipped with a digital camera. Magnification is the ability of a microscope to produce an image of an object at a scale larger or even smaller than its actual size.

By convention, for magnifying glasses and optical microscopes , where the size of the object is a linear dimension and the apparent size is an angle, the magnification is the ratio between the apparent angular size as seen in the eyepiece and the angular size of the object when placed at the conventional closest distance of distinct vision: 25 cm from the eye.
