Featuring an upright, unreversed image of three dimensional objects, the 452 is ideal for students. \u003c\/p\u003e \u003cp\u003eThe optical system consists of two widefield 10x eyepieces, with left-side diopter adjustment. The eyepieces are also equipped with a reticle holder\/retainer. The paired objectives are parfocalled, parcentered, and achromatic. Magnification is changed by turning the objective turret 90� to positive click stops.\u003c\/p\u003e \u003cp\u003eTo ensure a clear view of specimens, the microscope has a 4 position lighting control, allowing the student to turn on both lights or one at a time. Both top and bottom lights are tungsten. Also helping to see an accurate image is the rack and pinion focusing. Slip clutch and tension adjustments prevent damage to the system and keep the head from moving. Two locked-on stage clips keep the specimen securely attached to the microscope.\u003c\/p\u003e \u003c\/div\u003e \u003c\/div\u003e \u003cdiv\u003e \u003cdl\u003e \u003cdt\u003eOptical System\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003e Paired widefield 10x eyepieces, left-side diopter adjustment, interpupillary adjustment from 55mm to 75mm \u003c\/li\u003e \u003cli\u003e Eyepieces equipped with reticle holder\/retainer to accept reticle with 23mm O.D. \u003c\/li\u003e \u003cli\u003eFixed head\u003c\/li\u003e \u003cli\u003ePaired objectives are parfocalled, pacentered and achromatic\u003c\/li\u003e \u003cli\u003eMagnification changed by rotating objective turret 90� to positive click stops\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eIllumination\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003e4-position light control: top only \/ bottom only \/ top and bottom \/ off\u003c\/li\u003e \u003cli\u003eTop light (incidental) and bottom light (transmitted) corded 12V 10 watt tungsten illumination\u003c\/li\u003e \u003c\/ul\u003e \u003c\/dd\u003e \u003c\/dl\u003e \u003cdl\u003e \u003cdt\u003eBase\u003c\/dt\u003e \u003cdd\u003e \u003cul\u003e \u003cli\u003eRack and pinion focusing with slip clutch and tension adjustment\u003c\/li\u003e \u003cli\u003eIncludes two 80mm stage plates: frosted glass and reversible black and white plastic contrast plate\u003c\/li\u003e \u003cli\u003eTwo locked-on stage clips\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 452-TBL-10 Stereo Microscope\u003c\/div\u003e \u003c\/div\u003e \u003cul\u003e \u003cli\u003e5-Year Limited Warranty\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\u003eStereoscopic\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMagnification\u003c\/td\u003e \u003ctd\u003e1x, 3x\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eObjectives\u003c\/td\u003e \u003ctd\u003eNot specified by manufacturer\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eEyepiece\u003c\/td\u003e \u003ctd\u003eWidefield 10x, 20mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eLight Source\u003c\/td\u003e \u003ctd\u003eTop light: 12V 10 watt tungsten\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eOverall Dimensions\u003c\/td\u003e \u003ctd\u003eHeight: 12.25\" \/ 310mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eWeight\u003c\/td\u003e \u003ctd\u003e5.5 lb \/ 2.5kg\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.
