Sentence examples for simple microscope from inspiring English sources

Using his simple microscope, Leeuwenhoek effectively launched microbiology in 1674, and single-lensed microscopes remained popular until the 1850s.

A simple microscope can resolve below 1 micrometre (μm; one millionth of a metre); a compound microscope can resolve down to about 0.2 μm.

The work Darwin carried out in his gardens, greenhouses and home laboratory is particularly impressive, Ms. Falk said, given that he was limited to a simple microscope and equipment like "quills, matchsticks, bits of wire".

The traditional simple microscope was made with a single magnifying lens, which was often of sufficient optical quality to allow the study of microscopical organisms including Hydra and protists.

The limitations on resolution (and therefore magnifying power) imposed by the constraints of a simple microscope can be overcome by the use of a compound microscope, in which the image is relayed by two lens arrays.

Single-lensed simple microscopes can magnify up to 300× and are capable of revealing bacteria while compound microscopes can magnify up to 2,000×.

Simple microscopes using single lenses can generate fine images; however, they can also produce spurious colours due to chromatic aberration, in which different wavelengths of light do not come to the same focus.

(Early simple microscopes such as Leeuwenhoek's magnified up to 300×.) The image can be improved if the lens has specific aspheric surfaces, as can be easily obtained in a plastic molded lens.

Simple microscopes were used by Leeuwenhoek in the Netherlands in the seventeenth century, and here we will see that the design widely described as a "Leeuwenhoek microscope"—was actually a concept of the London philosopher, Robert Hooke.
