Cheap Close-up Camera Lens
designed by David Johnson, P.E. |
| I often use my digital
camera to take photos of some electronic projects. At times, I need to get in
close to capture some details. But, without some additional optics, my camera just
could not maintain focus, as I got closer to an object. Being a cheap person, I
didn’t want to spend money on an expensive close-up lens. |

Instead, I
found a 1.75” glass lens with a focal length of about 2.5 inches. I glued the lens to
a cardboard tube. This allowed the assembly to slide over the extended cylindrical
lens of my camera, holding the glass lens over the camera lens. Thicker glass lenses
could be used for higher magnification but this one allowed me to zoom in pretty
close. The PC board below is a 1GB memory stick IC with 0.025” pin spacing |
