High powerobjective microscope function

The ultimate magnification power of a microscope can be calculated by multiplying the magnification power of the eyepiece by that of the objective lens. If an object is viewed through a 10x eyepiece and a 4x objective, the image produced will have been magnified 40x.

The USAF 1951 resolution test chart is a standardized tool used to measure the resolving power of optical systems such as cameras, microscopes, and telescopes. Developed by the United States Air Force in 1951, this chart is still widely employed to test the clarity and sharpness of lens systems and imaging devices.

While a microscope is built of many parts, the cornerstone is in many ways the objective lens. The resolving power and total magnification power of the microscope as well as the quality of the final image all depend on the objective lens used.

A microscope objective lens produces a real, magnified image of an object placed within the field of view. Before it is observed the image is then magnified again by the ocular lens, also known as the eyepiece.

Just like widefield or confocal fluorescence microscopy, two-photon microscopy is based on fluorophore excitation, which results in the emission of light.

While the USAF 1951 chart has been widely used, it has some limitations in assessing modern, high-resolution imaging systems. As technology advanced, newer targets and methods have been developed for more rigorous testing of such systems.

It is commonly used in quality control, research, and calibrating systems to ensure consistent and reliable performance.

To interpret the results, each group and element on the chart corresponds to specific line pairs per millimeter (lp/mm), which defines the spatial resolution of the system. The observer identifies the group and element where the lines can be distinctly separated, which directly correlates with the system's resolving power in terms of line pairs per millimeter.

The design of the chart comprises a series of patterns consisting of three-bar targets of varying sizes and orientations. Each set of bars is grouped into elements and groups of progressively smaller size, defined by their dimension and frequency.

Objectives are designed to magnify an object by a certain coefficient; from 4x (a scanning objective) to 40x (a high power objective) up to 100x for an oil immersion lens. For ultimate flexibility, a microscope is often equipped with up to four objectives on a rotating nosepiece or turret.  If an objective lens has infinity-correction the magnification is equal to the reference focal length divided by the focal length of the objective.
