How can the resolution of a microscope be improved?

To achieve the maximum (theoretical) resolution in a microscope system, each of the optical components should be of the highest NA available (taking into consideration the angular aperture). In addition, using a shorter wavelength of light to view the specimen will increase the resolution.

What part of a microscope can you change to make the image clearer?

Condenser Lens: The purpose of the condenser lens is to focus the light onto the specimen. Condenser lenses are most useful at the highest powers (400x and above). Microscopes with a stage condenser lens render a sharper image than those with no lens (at 400x).

What is the resolution power of microscope?

The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object. The greater the resolving power, the smaller the minimum distance between two lines or points that can still be distinguished. The larger the N.A., the higher the resolving power.

What limits the resolution of a light microscope?

The resolution of the light microscope cannot be small than the half of the wavelength of the visible light, which is 0.4-0.7 µm. When we can see green light (0.5 µm), the objects which are, at most, about 0.2 µm. Below this point, light microscope is not useful, as wavelength smaller than 400 nm is needed.

Why is immersion oil used in 100x objective?

However, once you use the 100x objective lens, the light refraction when using a dry lens is noticeable. By placing a substance such as immersion oil with a refractive index equal to that of the glass slide in the space filled with air, more light is directed through the objective and a clearer image is observed.

Do Tardigrade have eyes?

Tardigrades — which grow up to a millimeter in length — swim with four sets of stubby legs that appear much too small for their bodies. Tardigrades can move their heads independent of their bodies, and some species have eyes. When you look at them under the microscope, they stare straight back, unfazed by humans.
