The stereo (two) eyepiece configuration is preferred by most researchers and students because of the superior depth of field and comfort compared to monocular microscopes. This model of the 446 stereo microscope has a paired 5x eyepiece delivering 5x and 15x magnification. Two achromatic paired objectives are parcentered and parfocalled to keep the specimen centered and focused when switching between the two magnification settings. The stageï¿½can beï¿½illuminated from aboveï¿½and\/or below using 10Wï¿½tungstenï¿½lightsï¿½activated by separate base-mounted On\/Off switches.ï¿½The top (incidental) light source has an adjustable beam to help optimize the brightness and contrast of the specimen. \u003c\/p\u003e \u003cp\u003eA user-friendly designï¿½complements theï¿½range of features that make the 446 stereo microscope a welcome addition to labs as well as classrooms.ï¿½The heavy-duty post-mounted adjustable viewing head permits use of specimen heightsï¿½up to 35mm \/ 1.4\", andï¿½is also capable ofï¿½360ï¿½ï¿½rotation to help share the eyepiece among colleagues and studentsï¿½without moving the microscope. The rack and pinion system has a single focus dialï¿½andï¿½includes a slip clutchï¿½mechanismï¿½toï¿½prevent mishandling. An adjustable interpupillary distance, left-side diopter correction, and reticle holder\/retainer provide the 446 series with the flexibility needed to create a customized viewing experience.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdl\u003e \u003cdt\u003eOptical System\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003ePaired 5xï¿½inclined eyepiece\u003c\/li\u003e \u003cli\u003e1x and 3x achromatic objectives\u003c\/li\u003e \u003cli\u003e5xï¿½and 15x magnification\u003c\/li\u003e \u003cli\u003eParfocalled, parcentered,ï¿½paired objectives\u003c\/li\u003e \u003cli\u003e75mm \/ 3\" working distance, 35mm \/ 1.4\" maximum specimen height\u003c\/li\u003e \u003cli\u003eEyepiece withï¿½diopter adjustment and reticle holder\/retainer\u003c\/li\u003e \u003cli\u003e55-75mm \/ 2.2-3\" interpupillary distance\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eFocusing\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eRack and pinionï¿½focus system\u003c\/li\u003e \u003cli\u003eSlip clutch prevents over-turning\u003c\/li\u003e \u003cli\u003eTension adjustment prevents focus drift\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eLighting\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eIncidental (top)ï¿½10 wattï¿½tungsten illumination with adjustable beam\u003c\/li\u003e \u003cli\u003eTransmittedï¿½(bottom)ï¿½10 wattï¿½tungsten illumination\u003c\/li\u003e \u003cli\u003eDual base-mounted On\/Off switches\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eConstruction Details\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003e80mm frosted glassï¿½and 80mmï¿½reversible black and white stageï¿½plates\u003c\/li\u003e \u003cli\u003eLocked on metal stage clips\u003c\/li\u003e \u003cli\u003e360ï¿½ rotating viewing head\u003c\/li\u003e \u003cli\u003eCast metal frame\u003c\/li\u003e \u003cli\u003eGrey enamel finish\u003c\/li\u003e \u003cli\u003e14.6\" (37 cm) maximum height\u003c\/li\u003e \u003cli\u003e5.5ï¿½lb (2.5 kg) weight\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e\u003cdiv\u003e \u003cdiv\u003eIn the Box\u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003eNational 446TBL-05 1x\/3x Stereo Microscope\u003c\/div\u003e \u003c\/div\u003e \u003cul\u003e \u003cli\u003eEyeshields\u003c\/li\u003e \u003cli\u003eDustcover\u003c\/li\u003e \u003cli\u003eLifetime Limited Warranty (Excluding Bulb)\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003cdiv\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eMicroscope Type\u003c\/td\u003e \u003ctd\u003eStereo\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eEyepiece\u003c\/td\u003e \u003ctd\u003e5.0x\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eObjective(s)\u003c\/td\u003e \u003ctd\u003e1.0x \/ 3.0x\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eHead\u003c\/td\u003e \u003ctd\u003eInclined\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eLight Source\u003c\/td\u003e \u003ctd\u003e12 V, 10 W tungsten (incidental\/transmitted)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eLight Control\u003c\/td\u003e \u003ctd\u003e4-position On\/Off\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eStage\u003c\/td\u003e \u003ctd\u003e80 mm frosted glass and reversible black\/white contrast plate\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eInterpupillary Adjustment\u003c\/td\u003e \u003ctd\u003e2.2 - 3\" (55 - 75 mm)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMaximum Specimen Height\u003c\/td\u003e \u003ctd\u003e1.4\" (35 mm)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMaximum Height\u003c\/td\u003e \u003ctd\u003e14.6\" (37 cm)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWeight\u003c\/td\u003e \u003ctd\u003e5.5 lb (2.5 kg)\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e\u003c\/div\u003e \u003c\/div\u003e \u003c\/div\u003e All product and company names are trademarks™ or registered® trademarks of their respective holders.
