Paul, the guy with vision around here, calls these the binocs to get if you're stepping up your binocular game. From Celestron®, they're Nature DX Series 8 x 42 and lightweight at about 22 oz with BaK-4 prisms, fully multi-coated optics, twist-up eyecups, 7.4 degree angular field of view (FOV), 6.5 ft near focus, linear FOV of 388 feet at 1000 yards, 17.5mm eye relief, 5.2mm exit pupil for brighter images and phase-coated optics. They're completely waterproof and nitrogen-purged to prevent fogging and are "perfect for birding" per Paul. Measure an easy-to-handle 5.3" x 4.9" x 2" and come with a case, neckstrap and chamois.

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. It has an upgraded 5-megapixel camera that can record 625 hi-res photos or 20 minutes of 30fps video to the included 1GB SD card. The 4X, 10X and 40X objectives provide 40X, 100X and 400X optical magnifications, and the digital zoom raises it up to 1600X. On-screen, button controlled settings allow you to easily adjust exposure, image effects, a digital measuring reticle and other visual tweaks. Top and bottom independently adjustable LED illumination and a built-in 6 position filter wheel allow complete light adjustability. Also included are an AC adapter with 3 extra European adapters for those who travel, (5) prepared slides, USB and video out cables and a rigid lined 15" x 7" x 8.5" OA carrying case with a suitcase-handle and shoulder strap, for storage, field work or classroom visits. Carries a 2-year manufacturer's warranty.

New, international-standard, full-sized illuminated student microscope, professional quality at a student price. Now comes with a variable intensity 5.5V LED cool illumination system with a built-in rechargeable battery and wall transformer for use or charging. It has turret-mounted achromatic objectives, fine and coarse rack-and-pinion focus and substage diaphragm light control, and a metal frame. It is built to international DIN standards and accepts all DIN eyepieces and objectives. With extras like focus stop for slide protection, adjustable tilt and (2) spring clips, it is a fine instrument for most home science work and projects in the field. If you are looking for more magnification purchase the spring loaded 100X (oil immersion) objective lenses. Brings your scopes total magnification up to 1000X magnification. Our (36) piece assorted specimen set comes on (12) slides. All are great additions.

Frees up your hands while you examine whatever you’re examining. The approx 2-1/2" dia acrylic lens is 2X (ignore the surplussing 2.5X on box) and is mounted in a black fold-out frame with a pair of white LEDs underneath the lens for your examining pleasure. Measures 4-1/4” long and includes 2 replaceable AG7 batteries.

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.

Nothing to it if you have these 20 x 70 binoculars with rubber-coated housing for ruggedness, blue-coated optics, and a K9 prism for sharp images. Great for camping, wildlife viewing, more and large enough for you to enjoy viewing the night sky. Measure 11-1/4” long overall and come with folding eye-cups, right-eye diopter adjustment, a standard tripod mount between the optics, adjustable neck strap and a carrying case.

Nothing is certain except death, taxes and smudges. Take care of at least one with these lens-cleaning kits. They include a 7”-square lens cloth, (5) double-headed swabs, and a 1-oz vial of ammonia-based cleaning fluid in a spritz bottle.

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.  

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.

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. All you add is (3) "AAA" batteries and a bunch of stuff for them to peer at, like insects and coins.

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.

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.

Made specifically for attaching to pill bottles, this 1-3/4" dia magnifier has a 2X acrylic lens with a blue tint that increases readability. It’s mounted on a ring and bracket with a rubber strap to hold it in place on the bottle and keep the lens an inch above the label/instructions.

Has the print in your books been getting smaller? Fight back using this 3-1/2" long plastic magnifier with (2) lenses. The 2x lens is 1-3/4" dia., while the 6x lens is 3/4" dia. Kids will love using it to explore bugs, crystals and leaves up close.

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.

Best done with this computerized StarNavigator 90mm Maksutov-Cassegrain telescope from Meade® Instruments.

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!
