What is thefunctionof arm in microscope

The objective lens is the lens closest to the object in the microscope and is the most important single part of the microscope. Since it determines its basic performance and function. It is responsible for gathering light and forming an image of the object.

electric polarization, slight relative shift of positive and negative electric charge in opposite directions within an insulator, or dielectric, induced by an external electric field. Polarization occurs when an electric field distorts the negative cloud of electrons around positive atomic nuclei in a direction opposite the field. This slight separation of charge makes one side of the atom somewhat positive and the opposite side somewhat negative. In some materials whose molecules are permanently polarized by chemical forces, such as water molecules, some of the polarization is caused by molecules rotating into the same alignment under the influence of the electric field. One of the measures of polarization is electric dipole moment, which equals the distance between the slightly shifted centres of positive and negative charge multiplied by the amount of one of the charges. Polarization P in its quantitative meaning is the amount of dipole moment p per unit volume V of a polarized material, P = p/V.

The eyepiece consists of two parts. The upper end of the lens which is closest to the observer’s eye is called the eye lens, its function is magnifies. The lower end of the lens which close to the object being viewed is called the convergent lens or field lens, which make the image brightness uniformity.

In summary, the eyepiece lens and objective lens in a microscope work together to enlarge image of observation specimen. The objective lens collects light and creates an enlarged image, eyepiece lens further magnified the image and presented to the observer. The combination of the two lenses determines the overall magnification and enables detailed examination of the specimen.

The objective lens consists of several lenses. The purpose of the combination is to overcome the imaging defects of a single lens and improve the optical quality of the objective lens.

An eyepiece, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes, is the lens that the user looks through. It magnifies the image formed by the objective lens, making it appear larger and easier to see. The eyepiece lens is also responsible for focusing the image.

The longer focal length eyepiece will provide a smaller magnification, while an eyepiece with a shorter focal length will provide a larger magnification. The focal length of the objective lens is a kind of optical property, it determines the distance at which the lens focuses light. It affects the working distance and depth of field but does not impact the magnification directly.
