FAQ - Frequently Asked Questions > Understanding magnification

Magnification is a matter of definition.

Normally we think of magnification on a digital microscope as the ratio of the shown size on the PC monitor compared to the actual physical size.

So if the object has a dimension of 1mm and displays on the monitor as 12.3cm, then the magnification is 123x (So also the monitor size and resolution is to be considered).

In short we calculate the magnification as:

Mt = Mo x Md x PSm / PSc;

Where:

•Mt is the total magnification

•Mo is the optical magnification

•Md is the digital magnification (like if you zoom using the mouse wheel…)

•PSm is the pixel size on the monitor (You need to set you monitor size in the DeltaPix InSight control panel, resolution can be read by the software).

•PSc is the pixel size in the camera.

Please consult the manual, section “Show Absolute or Relative magnification”.
