Magnifying Headband
Perfect for detail, hobby or jewelry work, for examining bugs and rocks and field specimens, even reading. An adjustable headband holds a flip-up visor. On the visor is a battery holde (2) "AAA", not included) and light which can be turned on and off and aimed where needed. Below the visor hangs a pair of magnifying lenses which can be flipped up out of your sight independent of the visor. (4) interchangeable acrylic lens sets are included, 1.2X, 1.8 X, 2.5X and 3.5 X. Quite well made and its patented design is thoroughly adaptable to whatever use.

Be(prism)am
Nice little cubic beamsplitter prism. (Get it?) 12 x 11 x 10mm, it's painted black on (3) sides. Low transmission-about 70/30 or 80/20-but it'll be fine for classroom demos, experimentation, or perhaps souping up your fancy laser device.

World's Best Lens Cleaner
Rexton lens and optical surface cleaner cleans all optical surfaces: lenses, mirrors, prisms, windows, slides and leaves no haze. It cleans plastic or glass camera lenses, coated or uncoated. We have given some to our telescope supplier, who is an expert in such matters, and he says it is the best he has ever seen. You can even clean painted and metal surfaces. Comes in an 8 oz squeeze bottle with a flip up squirter. Absolutely the last word in cleaning for optics.

Full Page Magnifying Sheet
Flat plastic Fresnel lens. This flexible magnifier is 7-1/4" x 10-1/4" and only about a millimeter thick. It is great when you need to scan a list or to look for something in a directory. You can see most of the page without moving the magnifier. Only about 1.5 power, but that can make a huge visual difference. The quality is not high, but neither is the price.

Camera Tripod
A tripod with true portability -- It weighs only 2 lbs, the 4-ft aluminum legs (which can be locked down independently at any length) telescope to a convenient 22", and it slips easily into a zippered black-nylon quiver. The mast, which has a standard 1/4-20 camera mount and a built-in level, can be cranked up (literally) another 9-1/2". The manufacturer doesn't say how much weight the tripod will bear, but we'd keep it to under 10 lbs. Very nice for the money.

Perfect Porta Pod
The in-between aluminum tripod: bigger than a mini but a lot easier to tote than a full-size version. Collapses to 14-3/4" long x a triangle approx 2-1/2" on a side. Has 4-draw legs with clutches that extend (3) feet, and a shaft that pulls up another 12" to a full 4-foot height. Includes a 1/4"-20 standard camera thread. Very useful item for small digital camera users.

Graticulated Magnifier
It is too a word. But never mind, this is a honey of an LED-illuminated, 8X magnifier with a 7/8" dia lens (ignore the 1-1/4" on the box) with an adjustable focus and a 10mm reticle marked in 1/10mm increments. Measures 1-13/16" tall x 2-7/16" wide OA with a 1-9/16" dia lens housing. Powered by (3) replaceable, and included, button-cell batteries.

Big Multi-Use Lens
This aspheric glass lens is 62mm (2.44") dia with a focal length of 42mm. Apart from your standard lens-ish optics applications, we think it also lens itself to use as an entertaining desktop spin toy, and we figure it would make a dandy bulls-eye in a leaded glass window.
