Microscopy (Principles)

The microscope's objectives and optical zoom system enable the magnification of minute substances of such samples
placed on the stage as metal, mineral, and cells, so that microscopy and image capturing are performed with the focus
adjusted using the focus device.
 Intended use of this product
This microscope is intended primarily for microscopic observations, experimentation and image capturing of samples
(metal, mineral, cells, etc.) placed on the stage, using diascopic and reflected illumination. Therefore, accuracy of the
numeric information (such as magnifications or Z-position information) is not guaranteed. These values are used as
reference and include a margin of error.
