This is the first proper nano-gigapan using the a modified gigapan unit attached to a scanning electron microscope (SEM). The image was then assembled was then stitched using the gigapan stitching software. The image is of an ants head at 1000X magnification.
Brian Fisher, the chair of entomology at the California Academy of Sciences identified this ant as a Linepithema humile. More information about this ant can be found in the following two links:

Great Job! I would really really really like to know how to do these types of photos. Can you post here the equipment you used and how you modified your gigapan? or email me at "jmurray6834" at yahoo dot com? Thanks! Posted by jmurray |

Very Cool. Is this the equipment that Rich helped with? Hopefully you will be shooting some more of these. jmurray, you may need to go to the nearest university physics department and hope that they have a scanning electron microscope. http://en.wikipedia.org/wiki/Scanning_electron_microscope Posted by DiscoveryLatin |

Yes, Rich did help with this a lot, without his encouragement, it wouldn't have happened. Jmurray, the stepper motors of the gigapan have been brought out to the xy stage of a Hitachi TM-1000 desktop SEM. It's fairly straightforward, though as DiscoveryLatin pointed out, the crucial bit is the SEM. I'll try to post some more information about the setup later. Here is an image of the setup: http://www.flickr.com/photos/ordaos/3507149729/ Thanks for the enthusiasm, it's got me taking more :) I'm looking at salt crystals right now and will post the results soon.

The Nanopan is very cool! Does the SEM normally have manual knobs for adjusting the stage, and you hooked the steppers up to their posts? Did you use a 'Digital' shutter release or do you have a servo finger pushing a button on the microscope;) ? Did you have to modify the Gigapan firmware at all or adjust any revolution settings? What about hooking up such a setup to a regular microscope to get some nice color photos? Maybe even do some focus stacking on a optical scope and have some big depth of field! Posted by odyssey |

Odyssey, This SEM does have manual knobs, it's a very simple SEM. I've simply attached the stepper motors to the knobs using some flexible tubing. I'm not using a digital shutter yet, doing it by hand, it's very time consuming, about a minute per picture. I hope to be able to make a macro on the computer to automate this, which can be triggered by the servo finger pressing a key or something. I didn't modify the gigapan firmware, it's all kept as-is.
