Pixels Map Length to Addresses

Magnification Scales Length

sample to image

A schematic optical image length is checked from magnification. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

The sample segment has a checked length

The sample segment is 3 m.

Magnification scales the image length

The magnification is 4, so the image length is 12 m.
