National Optical

The rechargeable battery-powered 131-RLED-MS Compound Microscope with Mechanical Stage from National Optical is a three-objective inclined microscope designed for middle school and high school students. Achromatic DIN optics minimize image distortions and deliver consistent views on all three magnification settings. The objectives are also parfocalled and parcentered, keeping the specimen in focus and centered in the field of view when the magnification is changed. This microscope was built for reliable performance and is backed by the manufacturer's lifetime warranty.A user-friendly design complements the range of features that make the 131 series microscope a welcome addition to classrooms. A 360 rotating monocular viewing head enables the eyepiece to be shared with multiple viewers without having to move the microscope. This configuration of the 131 has an individual focus dial for fine and coarse adjustments. The focus system also includes a slip clutch and rack stop that prevents mishandling by novice users. The 131-RLED-MS also features a rechargeable battery-powered cool LED substage illuminator and graduated mechanical stage. National Optical engineered this compound microscope to be durable, portable, and feature-rich enough to help transition high school students to more sophisticated instruments.Optical System 10x, 18mm eyepiece with revolving pointer4x,10x,40xR color-coded DIN objectives40x,100x, 400x magnificationRotating objective turret with click stopsAchromatic, parfocalled, parcentered objectives360 rotating head for easier eyepiece sharing45 inclined monocular eyepieceFocusing Separate fine and coarse focusing controlsRack-and-pinion focus systemSlip clutch prevents over-turningTension adjustment prevents focus driftRack stop prevents damage to slides and protects lensesLighting LED illuminator (20 Watt equivalent)0.65 condenser lens5-hole disc diaphragmCordless LED illuminatorUp to 50 hours or runtime on 3 rechargeable NiMH AA batteriesConstruction Details Graduated mechanical stageCast metal body with inclination jointGrey enamel finish14" (36cm) height6.8 lb (3.1 kg) weight
