The submicroscopic scale similarly includes objects that are too small to see even with any optical microscope.

During this stage of the cell cycle this makes the individual chromosomes in many cells visible by optical microscope.

These conical pits are usually of micrometer dimensions and can be observed with an optical microscope.

Two kinds of optical microscope are generally used to examine flat, polished and etched specimens: a reflection microscope and an inverted microscope.

The image from an optical microscope can be captured by normal light-sensitive cameras to generate a micrograph.
