Hi - My name is Jim White and I provide public programming using the Science Center's Hitach S-3500N scanning electron microscope (SEM). The Orlando Science Center is one of the few places in the US where the public can get up close and personal with an SEM and see its capabilities. The SEM has many advantages over light/optical microscopes and I will explain those in future posts. Some of its capabilities include high magnification (up to 100,000X in optimum conditions) and elemental analysis.

I choose from a variety of samples to observe each day I am here. Some of the items we have observed in the past include bugs, fibers, and coins.

Currently, I mainly do programs on a few weekend days a month. I will be posting my schedule as it is firmed up so you will know when I will be here and you can, hopefully, come by the SEM laboratory on Level 4 at the back of DinoDigs.

I will be posting a new blog at least every two weeks and will be talking about items dealing with the SEM as well as other subjects that I think you will find interesting.

Hope to see you soon,
"SEM Jim"
