|Calculator Circuit Board - f/22 - Infrared|
This particular chip is from an inexpensive "give away" calculator that died. I took apart the case and found this chip with its interesting pattern of circuit lines. The finger connectors at the top were connected to an LCD display which I removed.
The photograph was taken with a Nikon D90 that was converted to a standard infrared camera (720nm) by LifePixel. I used a Nikkor 105mm VR f/2.8 macro lens. The chip is tilted away from the camera so I had to use a very small aperture (f/22) to get everything in focus. Lighting was from an overhead halogen light.
You don't have to leave your IR camera in the closet during the winter or use it for a paperweight. IR photography can happen all year long.
