You'll love this 3-draw, brass, 25x30 spyglass-style spotting scope from Celestron®. Extends to 13" and contracts to 5-3/8" with an adjustable focus at the eyepiece. Comes with a sewn-on leatheresque cover (very piratical), a polishing cloth and a much-better-than-average wooden case.

These white microfiber cloths are larger, at 6" x 7-1/2",  and thicker than usual. Made for medical equipment (so you know the quality is excellent), they're dandy for eyeglasses, lenses, computer screens and other electronic equipment. White with a dark blue edge (with a small logo in one corner) they're actually attractive and could double as pocket squares. Bundled by the pair so you'll get (6) cloths in our Pkg(3), or try our super low 20-pair price.

Serious high resolution 80mm dia binoculars with a 15-45X zoom, for serious gazing. These big boys measure 13" long and weigh 4.6 lbs (they have a 1/4"-20 tripod mount) and have coated optics, a rubberized housing, roll-back eyecups, interpupillary adjustment (say that ten times fast) and focus, and a variable zoom from 15X to 45X. They come with a chamois, neck strap and a padded, zippered black leatherette carrying case with a strap. Not for the opera, unless you really want to see the fat lady's tonsils. Near focus of approx 25 feet. Great viewing, whether you're into wildlife or astronomy. Includes a 2-year manufacturer's warranty. Makes a great gift!

The sport of the future? No, cork-lined polystyrene boxes for holding microscope slides, complete with numbered slots and inventory sheets on the lids. The boxes are 8-3/4" x 6-3/4" x 1-1/3" with hinged lids. They are stackable, and you might get them in a variety of colors.

A Sherlock Holmes-type magnifying glass is good, but this is better. It frees your hands and throws light on the subject! This 120-volt magnifying desk lamp has a heavy 7-3/8" x 5-1/2" x 2" base with a power switch, standard lamp cord, and 11" gooseneck ending in a 5-1/4" dia shade. Under the shade is a circular fluorescent bulb and a 3-3/8" dia lens with a flip-back cover. The box says the lens is 5X, we think it's closer to 2X. Either way, it's a major improvement if you need help to examine scientific specimens, to inspect stamps or jewelry, or just to read. And we won't even talk about how your nail care is going to improve after you see your cuticles under this thing!

This giant 5" dia magnifier stands alone, 10" above a base with a mm/inches plotting scale, like a giant linen tester, but folds nearly flat for easy storage or portability. The large lens is 2X with a 5/8" dia 2X bifocal inset (ignore the description on the box). Illuminated by a very bright white LED. for which you need to bring (3) "AAA" batteries to the party. White plastic and chromed metal.

You’re bound to be able to read through one of the lenses on this triple-lens hand-held magnifier. You pick. There’s a large, 5-1/4” acrylic lens at 1.5X with a 1” dia bifocal on the left at approx 2X and a doublet in the handle at approx 7X. (Ignore the surplus-inducing mis-marked lens powers; we tested ’em and the powers listed here are accurate.) Has (3) white LEDs under the main lens for your viewing pleasure and measures 10-3/4” long . The other is the same thing in a slightly smaller size, 8-3/4” long overall with a 3-3/8” x 1.5X main lens with a 1” dia bifocal on the left at approx 3X and a doublet in the handle at approx 7X. You add (3) “AAA” batteries for the LEDs.

One wiseacre assumed we meant any package leaving our shipping room that once had a glass object in it. That is a malicious rumor. . . Ground glass is thin plate glass, the surface of which has been physically ground or acid-etched to create a grainy, grayish, opaque surface. Use it to produce an image from a lens or lens system. Even a simple magnifier, held between the ground glass and, say, a window, will produce an image of the window scene on the ground glass. Ground glass has another magical property: it is opaque to any object viewed at a distance, but not if that object is in direct contact with the glass surface. A necessary element of your optical education. #2728 (square) is 2"sq x 1/32" thick. #2610 (rectangular) is 3-1/2" x 4-3/8" x 1/16" thick.
