2. Ramsden eyepiece: This design features two plano-convex lenses with the convex sides facing away from each other. It offers a wider field of view compared to the Huygenian eyepiece and is commonly used in modern microscopes.

A question commonly asked about compound microscopes is: What’s the purpose of having 3 objective lenses attached to it? The answer is quite simple.

While the basic 3 objective arrangement still dominates today, some microscopes incorporate additional objectives or special enhancements for increased performance and capabilities.

The magnification power of the eyepiece is a measure of how much the image is enlarged when viewed through the microscope. This is usually expressed as a number followed by an "x" (e.g., 10x, 20x), which indicates the number of times the image is magnified. For example, if the eyepiece has a magnification power of 10x and the objective lens has a magnification power of 40x, the total magnification of the microscope would be 400x (10x multiplied by 40x).

The range of magnifications enables users to choose the appropriate level for their particular application, whether surveying tissue architecture or examining subcellular organelles. No single objective lens can provide optimal performance across this wide range of viewing needs.

Proper illumination from below is vital for viewing clarity. The maximum resolution or resolving power is limited by the wavelength of light and optics. Higher quality objectives provide greater usable resolution to see fine details.

From a modern perspective, the eyepiece on a microscope may also be designed to reduce eye strain and provide a comfortable viewing experience. Some eyepieces are equipped with adjustable diopter settings to accommodate individual differences in vision, and others may incorporate anti-glare or anti-reflection coatings to improve image clarity.

The multiple objectives with parcentered optics allow users to quickly switch between lenses and magnifications to obtain just the right view. This facilitates efficient and intuitive workflows.

The lowest magnification objective is typically a 4x or 10x lens. Its primary purpose is to provide a wide field of view of the overall specimen on the slide for initial orientation and scanning. The low magnification reduces aberrations from optical imperfections.

The 40x or 100x high power objective produces the highest magnification and resolution to reveal subcellular structures and other intricate details not discernable with the lower powered lenses but has an extremely narrow field of view. It is used for critical inspection of key areas after initial surveys with lower-powered objectives.

The eyepiece on a microscope, also known as an ocular lens, is the part of the microscope that is looked through to view the magnified specimen. It is located at the top of the microscope and is the lens closest to the eye of the observer. The eyepiece is designed to magnify the image produced by the objective lens, which is the lens closest to the specimen being observed.
