3-D Specs
You remember: white cardboard frames with red and blue plastic lenses. The temples fold to 5" long. 3-D's a lot more fun in these days of the Web: go to www.howstuffworks.com for binocular disparity and rivalry tests, or just Google around to find fun stuff or school optics experiments to use these with.

Top Quality Commercial Magnifiers
Small folding handheld inspection glasses of higher power than readers. The tradeoff for high power is a small field of view and a short working distance. We offer an imported 10X doublet jeweler’s loupe mounted in a metal case. Great for pocket or purse.

First Surface Mirrors
Optical imaging folk insist that their reflective surfaces be on top of the glass, because an optically minor “ghost” is created with back surface mirrors. These “First Surface” optical mirrors generally also have better glass and flatter surfaces than their household brethren. Delicate, with the fragile reflective surface exposed, they carry the prices that precision demands. If you are playing with lasers, photography or optical alignment, the first surface items below are what you need. Dimensions are included in the description as width x length x thickness, all in mm.

A Pyramid of Prisms
Polished glass equilateral prisms. Equilateral because each edge of the end is the same length, 32mm. Thus, as all you geometry students know, each of the angles is also the same, 60 degrees. These are school grade and are fine for decorative and demonstration. They do a nice job of diffracting light to produce a nice rainbow-like spectrum, but are definitely not up to instrumentation standards. The missing dimension, length, is shown below.

Closeup
Designed for watchmakers, this aluminum loupe with a 1" dia, 10x glass lens snugs to your eye, but leaves your hands free, thanks to the flexible 15" headband that encircles your head. It has a 1-1/2" working distance, and would come in handy, too, if you poke around in needlepoint or manipulate anything miniature.

Bend It Like Newton
…with this clear-acrylic triangular prism, 25mm x 50mm long (1" x 1-15/16"). Perfect for light refraction lessons--especially for younger kids, since the plastic won't chip like glass will--and for showing how Sir Isaac figured out rainbows way ahead of all the other kids.
