The 0.75-4.5x eyepieces combine with the 10x objective for a magnification range of 7.5-45x, and the overall height adjusts 13.4-17\" to accommodate larger objects. The large zoom ratio of 6:1 and a standard working distance of 110mm provide the flexibility to support a large number of potential applications while the addition of an auxiliary lens or substitute eyepieces extend the magnification up to a maximum of 180x.\u003c\/p\u003e\n   \u003c\/div\u003e\n  \u003c\/div\u003e\n \u003c\/div\u003e\n \u003cdiv\u003e\n  \u003cdiv\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cdiv\u003e\n      \u003cdiv\u003e\n       Optical System and Focusing\n      \u003c\/div\u003e\n     \u003c\/div\u003e\n     \u003cdiv\u003e\n      \u003cdiv\u003e\n       \u003cul\u003e\n        \u003cli\u003ePaired widefield 10x eyepieces are 45° inclined, with dual diopter adjustments, interpupillary adjustment from 55-75mm\u003c\/li\u003e\n        \u003cli\u003eAccepts 23mm eyepiece reticle\u003c\/li\u003e\n        \u003cli\u003eViewing head rotates 360°\u003c\/li\u003e\n        \u003cli\u003eContinuous magnification 7.5-45x\u003c\/li\u003e\n        \u003cli\u003eLarge dual focusing knobs with slip clutch to prevent damage to mechanism\u003c\/li\u003e\n        \u003cli\u003eTension adjustment eliminates focus 'drift'\u003c\/li\u003e\n       \u003c\/ul\u003e\n      \u003c\/div\u003e\n     \u003c\/div\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cdiv\u003e\n      \u003cdiv\u003e\n       Frame and Stage\n      \u003c\/div\u003e\n     \u003c\/div\u003e\n     \u003cdiv\u003e\n      \u003cdiv\u003e\n       \u003cul\u003e\n        \u003cli\u003eProfessional all-metal frame, gray enamel finish\u003c\/li\u003e\n        \u003cli\u003eHeavy-duty post mount with locking support collar permits up or down adjustment of viewing head to accommodate different sized objects on stage\u003c\/li\u003e\n        \u003cli\u003eHeight adjusts 13.4-17\" for larger objects\u003c\/li\u003e\n       \u003c\/ul\u003e\n      \u003c\/div\u003e\n     \u003c\/div\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n  \u003c\/div\u003e\n \u003c\/div\u003e\n \u003cdiv\u003e\n  \u003cdiv\u003e\n   \u003ch4\u003eIn the Box\u003c\/h4\u003e\n   \u003cul\u003e\n    \u003cli\u003e\u003cspan\u003eNational Optical 440-440P Zoom Binocular Stereo Microscope (Plain Base)\u003c\/span\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003cspan\u003eRubber Eye Shields\u003c\/span\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003cspan\u003eVinyl Dust Cover\u003c\/span\u003e\u003c\/li\u003e\n    \u003cli\u003e\u003cspan\u003eLimited Lifetime Warranty\u003c\/span\u003e\u003c\/li\u003e\n   \u003c\/ul\u003e\n  \u003c\/div\u003e\n \u003c\/div\u003e\n \u003cdiv\u003e\n  \u003cdiv\u003e\n   \u003ca\u003e\n    \u003cdiv\u003e\n     \u003cdiv\u003e\u003c\/div\u003e\n     \u003cdiv\u003e\n      \u003cp\u003eUser Manual\u003c\/p\u003e\n      \u003cp\u003e0.6 MB\u003c\/p\u003e\n     \u003c\/div\u003e\n    \u003c\/div\u003e\u003c\/a\u003e\n  \u003c\/div\u003e\n \u003c\/div\u003e\n \u003cul\u003e\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n \u003cdiv\u003e\n  \u003cdiv\u003e\n   \u003cdiv\u003e\n    \u003cdiv\u003e\n     \u003cdiv\u003e\n      \u003ch2\u003eNational Optical 440-440P Specs\u003c\/h2\u003e\n     \u003c\/div\u003e\n    \u003c\/div\u003e\n   \u003c\/div\u003e\n  \u003c\/div\u003e\n \u003c\/div\u003e\n\u003c\/div\u003e\u003cbr\u003eAll product and company names are trademarks™ or registered® trademarks of their respective holders.
