Great little glass DCX lenses for all of your project needs.  Utilize their 48.3mm focal lengths for all classroom projects, or combine these with other lenses to build binoculars, magnifiers, microscopes and telescopes. These are seconds so may have small chips.

Our newest Celestron® compound (biological) microscope is even better than the last one we offered. This one comes with a 3.5" color LCD viewing screen that rotates 180° for easy sharing in a lab, classroom or at home.

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.

My First Microscope from GeoSafari® Jr.® is a colorful plastic 8X binocular inspection scope for pre-preschoolers. Includes a built-in white LED top illuminator, over-sized rubber eyecups and simple focus knob. Fixed stage holds flat or 3D objects, so there's no need for slides.

Get 5ml of microscope slide stain in a nifty plastic squeeze bottle with a dropper top and white plastic screw cap. Bottle is approx 2" tall x 3/4" dia, like a standard food-coloring dispenser. You pick red or blue stain.

Our best-looking magnifier ever, the 2.5X, 3” dia frameless acrylic lens has a 5X, 3/4” dia inset and is attached to a streamlined heavy chrome handle, sort of like those hipster designer razors have. Comes in a reinforced zippered case with a chamois and a lifetime guarantee from the manufacturer Levenhuk®. Model Zeno 100. Ignore the pic with LEDs on the box. (This one’s prettier anyway.)

Cardboard binoculars are for observing paper lions. (Mahogany binoculars are for watching wooden performances, but we don't sell those.) These binoculars fold very nearly flat to 3" x 4" and magnify 3X through acrylic lenses. Flex them when they're unfolded and the focus adjusts somewhat. They're really made and priced for kids, are much better than they have any right to be, and can even be taken apart and used in a science fair telescope! Bonus: We'd keep some in the briefcase and glove box, we would.

Our tabletop telescope from Celestron is an excellent choice for traveling or as a first telescope, which explains its “FirstScope” name. It’s a 76mm reflecting telescope with 20mm (15X) and 4mm (75X) 1.25” eyepieces and mounts for a finderscope. The mount/stand has a lazy-susan style swivel and a variable tension knob. The Accessory Kit includes 12.5mm (24X) and 6mm (50X) 1.25" eyepieces, a moon filter, a 5X24 finderscope, planetarium software ("THE SKYX") for Windows 7, XP, Vista, Mac 10.4.8 or later, a nylon carrying case for accessories.

You get a half-dozen of these 2-1/2" dia x 3/32" thick back-surface mirror glass discs. Call it the crafter pack. What you do with them is a reflection on you, or perhaps a reflection of you. Made in the USA.

Microscopy marches on.

This binocular microscope for the serious science student is extremely well-priced. Magnification is determined by color-coded 4X, 10X, 40X and 100X oil-immersion objectives and (2) 10X eyepieces, for 40X, 100X, 400X and 1000X magnification. It offers a 110-volt, 1-watt LED substage illumination, interpupilary adjustment, rack-and-pinion coarse/fine focus, an iris diaphragm, and a mechanical stage with an Abbe condenser. It has a comfortable 45° viewing angle. Brand new, and at a terrific price! It also includes a 1 year warranty w/proof of purchase.  

Al Luebbers, our founder, collected glass. Not glass like you'd find on a knick-knack shelf, but optical glass. Lenses, prisms, reticles and filters, for example. Focus on the filters. Many of his filters came out of military surplus, and this is for-real stuff. We mean many are solid dyed optical glass, ground and polished to flatness standards that were probably excessive. Others are from the old days in photographic optics, and their standards were even tighter than your militaristic Uncle's. We've found that photographers, artists, and optical designers still have an occasional need for good glass filters, so we're making a list of some goodies. As always, don't be timid about calling for quotes on quantities. If we have 'em, we'll sell 'em. Just don't sell them back. Please!

Brand spanking new military surplus. New/old if you will. Perfect project mirror for light experiments. It is back surface. (That means the mirror coating is behind the glass.), some may have clear enough backs to be used as front surface mirrors, so bonus for you! 22mm diameter and only 1.5mm thick. Buy a bunch they are cheap!
