Manufactured in the USA by Edmund Scientific, the 2769 is the industry standard. It has a cutaway base which leaves enough room for strippers to get a knife under the lens. Great for countless uses where plenty of space under the lens is needed. The double achromatic lens system is mounted in a sturdy black anodized aluminum casing with adjustable ring lock focusing. The base is made of crystal clear acrylic to permit adequate light on the object. The 2769 magnifier has a lens diameter of 1 1/2″ and stands 3″ high.
