Cheap Close-up Camera Lens
designed
by David Johnson, P.E. (4/1/2005) |
| 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 received 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 |
