Super-light Magnifier/Fire Starter
At home it's a very nice giant magnifier, a 6-1/8" dia 3X Fresnel lens with a 4-3/4" long plastic handle and a bright, if badly placed, LED. At a campsite it's a Fresnel fire-starter whose big lens is light and flexible enough to fan the flames. The best part? Even with the (2) coin-cell batteries that come in it, it's almost weightless, a nice change from heavy glass magnifiers.

14mm x 28mm
They may be a little dirty, but that's a small price to pay for a glass achromatic lens at this small price. Small in size but a big value at 14mm dia. x 28mm focal length.

DCX Lens
This nice handful of plastic lenses is just the ticket for a primary-school teacher who needs unbreakable samples, and who wouldn't mind having a few interesting pieces left for craft projects. Each DCX lens is 20mm dia, 34.5mm focal length. Not individually wrapped, so a few may have small surface scratches.

Combo-Scope
The manufacturer of this great little device, C&A Scientific Company Inc., calls this a Spy Scope, but we think its multiple optical applications in one very small package are the story here. The very cool 8 X 20 spotting scope has an adjustable focal length graduated from 25cm to infinity. It measures a mere 4-7/8" long when extended, with a rubber grip and eyepiece cover and wrist strap. And it comes with a 3-1/4" tall 5X loupe that's threaded to mate with the scope to create a 25X microscope. The plastic microscope stand/extender is also threaded and will come apart from the loupe. Comes with a black nylon belt pouch for the spotting scope. Can you say "multi-task?"

Read 'Em without Weeping
When you need that print to be just a tad bigger and brighter, whip out your light-up, fold-out acrylic bar magnifier. The 4" long x 1-1/8" wide x 5/8" thick convex bar swings out of a 5" long black plastic case, lies flat, and magnifies approx 2X. Runs on 2 "AAA" batteries (not included) and is lit by a replaceable flashlight bulb (included). Just the right size, by the way, for a column of newsprint.

It's A Racket
It's a very nice magnifier, really, but it looks just like a little tennis racket. Measures 5-3/4" long with a glass, 48mm 2X magnifier and a small 14mm 5X lens just above the handle. Green-plastic frame with an orange faux-wrapped handle. Pay no attention to the 9X/5X on the box--what do lens grinders know about tennis?

Fiber Optics
The wave of the future. Create your own ISP or long-distance phone company. The plastic fiber-optic cables are clear, 1/32" dia single strand. Unjacketed is IFC-U1000, 1000nM. Jacketed cables are encased by black plastic, 1/16" OD, IFC-E1000, 1000nM. What do modelers do with it? A recent magazine on model railroading showed how to build a lighted marquee using fiber optics. Pretty neat!! The big boys get $1.60 to $1.90/per foot for this stuff!! All fiber optics sold in 10-ft lengths. Extremely neat!!
