The utilization of 400x magnification in phase contrast microscopy ensures no detrimental impact on the specimens, thereby facilitating the safe observation of healthy samples in their pristine, unaltered condition. For the purpose of sperm assessment, an adequate level of magnification is crucial, typically amounting to 400x. This level of magnification is commonly attained through the combination of a 40x objective lens and a 10x ocular lens.

Its Edge detection capabilities are indeed exceptional. And under this level of magnification, one can barely discern any details, yet it manages to reveal with clarity.
As a rule of thumb, the resolving power necessary to discern every intricate detail within a telescopic image corresponds roughly to half the aperture size measured in millimeters. However, in practical applications, a slightly higher magnification is often necessary, such as 1.5 times this baseline figure, translating to a magnification of 60x for an 80 mm aperture, which is a commonly employed standard for the purpose of sunspot enumeration.
Bacteria, due to their minute size, necessitate the utilization of a microscope for observation. While a few eucaryotic organisms, for instance, protozoa, algae, and yeast, can be visualized under magnifications ranging from 200X to 400X, the vast majority of bacteria necessitate a 1000X magnification for clear visibility.
A suitable magnification range for nature observation lies between 10x and 14x, with 10X being the prevalent choice. When it comes to 20x magnification, it offers a reduced field of view, necessitating close proximity to the eye for proper focusing, making it more suited for specialized applications. Magnifications exceeding 20X are typically reserved for experts in fields such as jewelry appraisal and diamond trading.
A loupe, pronounced as "/ˈluːp/ LOOP", represents a compact yet efficient instrument that facilitates a closer examination of minute details. It boasts a higher degree of magnification compared to a standard magnifying glass, tailored for use either handheld or positioned in proximity to one's eye for optimal viewing.
In the original source document, various drawbacks associated with heightened magnification are discussed (refer to Figure 1). These drawbacks encompass: A diminished visual range A shortened operational proximity A decrease in the focal plane's extent Enhanced illumination requirements Heightened challenges for patients during usage...
At a magnification of 400 times, one can discern individual cells along with a greater portion of their "constituents." Heightened magnification often correlates with a boost in resolution, thereby revealing finer details.
Under a 400x magnification lens, one can observe bacteria, blood corpuscles, and microscopic protozoa in their motile states. When the magnification is increased to 1000x, these very same entities remain visible, albeit in a more intricate, magnified detail.
Magnifiers, typically surpassing the dimensions of handheld lenses, provide magnification within a spectrum ranging from 2x to 8x. Their augmented lens dimensions translate to a substantially expanded visual field, a notable advantage over employing a handheld lens.
