Stop the
diagnosis of cancer, HIV and Ebola because high magnifications are impossible.
Magnification
occurs when we focus on a smaller area as if it were larger, which happens when
we bring an object closer or look through a lens or into a cylinder. It increases
as we move further from the object or use a thicker or additional lenses. However, there are limits to magnification.
There would be
limits to microscope magnification because the point is reached where we focus
on the lens itself so that blurring, distortion, reduction and loss of visibility occur. In a microscope, the diameter of the final lens
is too small, the tube is too short and too dimly lit, and the slide too close
to the lens to optimise lens magnification. Instead, we are viewing a
projected complex image of an object placed inside the microscope, the lens of
our own eye above that, and the stain from the slide.
