Photograph of the tracks on a Compact Disc. Track distance (line pair width) is 1.6 µm.

Pits of a Compact Disk

The setup (beautiful, isn't it?):

- the CD is held by Blu-Tack

- The two microscope lenses are aligned by their bottom, then taped together.

- Canon PowerShot G2 was placed on the metallic plate, was zoomed in, then pushed to touch the lens.



I have no plans to preserve this setup
