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 theï¿½452 stereo microscope has a paired 15x eyepiece delivering 15x and 45x magnification. Two achromatic paired objectives are parcentered and parfocalled to keep the specimen centered and focused when switching between the two magnification settings. \u003c\/p\u003e \u003cp\u003eThe 452TBL-15-LEDï¿½microscope canï¿½illuminate specimensï¿½from aboveï¿½and\/or below usingï¿½cordless LEDï¿½lightsï¿½activated by separate base-mounted On\/Off switches.ï¿½LED lightingï¿½is suitable for microscopyï¿½because ofï¿½its cool operating temperature, relatively white color temperature, and energy efficiency. The cordless LED lights will provide up to 50 hours of illumination after a full eight-hour charge. 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 make the 452 stereo microscope a welcome addition to classroomsï¿½as well as labs.\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 15xï¿½(20mm) inclined eyepiece\u003c\/li\u003e \u003cli\u003e1x and 3x achromatic objectives\u003c\/li\u003e \u003cli\u003e15xï¿½and 45x 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¿½cordless LEDï¿½illumination\u003c\/li\u003e \u003cli\u003eTransmittedï¿½(bottom)ï¿½cordless LEDï¿½illumination\u003c\/li\u003e \u003cli\u003eUp to 50 hours of continuous operation on a full charge\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\u003eCast metal frame\u003c\/li\u003e \u003cli\u003eGrey enamel finish\u003c\/li\u003e \u003cli\u003e12.2\" (31 cm) 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 452TBL-15-LED 1x\/3x Stereo Microscope\u003c\/div\u003e \u003c\/div\u003e \u003cul\u003e \u003cli\u003eEyeshields\u003c\/li\u003e \u003cli\u003eDustcover\u003c\/li\u003e \u003cli\u003eFive Year Limited Warranty (Excluding Bulb and Batteries)\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\u003e15.0x (20 mm)\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\u003eLED (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\u003ePower Supply\u003c\/td\u003e \u003ctd\u003e(3) rechargeable AA batteries\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eRuntime\u003c\/td\u003e \u003ctd\u003eUp to 50 hours\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\u003e12.2\" (31 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.
