These are a great bargain! Included is a focusing 8x20 monocular with 2 prism erecting assembly (focuses from about 6 feet to infinity), and a focusing loupe magnifier. Attach the eyeloupe (screws in) to the monocular and you have a very powerful 25X microscope. Glass optics, 3 element Kellner style eyepiece, and cemented doublet achromatic objective lens. Adjustments are very smooth and optics are fully coated. Included are: monocular (with wrist strap attached), loupe magnifier, and cleaning cloth! Unused/New. Great to carry in your pocket or purse for shows, sporting events, wildlife, etc. Sharper Image sells theirs for $59.95 and Jomira advertises them in Science News Magazine for $59 without the microscope attachment ($29.50 extra for it). This is an $88.50 value for an amazing low price here at Surplus Shed. One of our customers advises that this also works great for seeing to solder surface mount resistors and capacitors. Thanks Krissie. This Pocket Monocular/Microscope also makes a great gift for anyone!
