OMAX M82BE Binocular Biological Compound Microscope, 40X-2000X Magnification

OMAX M82BE Series Binocular Biological Compound Microscope, 40X-2000X Magnification. The M82BE series lab microscope is an updated version of OMAX's best-selling model, with a revised illumination system which can now be battery-powered. All of the features are still here, including an adjustable binocular viewing head and precision mechanical stage controls and focusing. The compact design has made this product line popular among schools, clinics and enthusiasts alike. Now it can even be used on the go. Viewing Head The binocular viewing head has a comfortable 45° incline for viewing while seated or standing, and can be swiveled 360°. Ocular spacing can be easily customized using sliding interpupillary adjustment. Dual diopters allow both eyepieces to be focused independently. Optics The microscope is equipped with four objective lenses mounted on a rotating turret to quickly move through the various magnifications. The lenses use DIN international standards, and are achromatically corrected to improve clarity and color accuracy. They provide a magnification range from 10X to 1000X when used with the standard 10X eyepieces, ideal for viewing a wide range of specimens including cellular structures and bacteria. Additional 20X eyepieces are included to expand the maximum magnification to 2000X with 8 unique levels. Objective Lenses Magnification Corrections NA Immersion Medium Cover-glass Thickness 4X achromatic 0.10 - 0.17mm 10X achromatic 0.25 - 0.17mm 40X achromatic 0.65 - 0.17mm 100X achromatic 1.25 oil 0.17mm Specimen Stage The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level. Dual-powered LED Illumination The LED sub-stage lighting provides cool, energy-efficient illumination. The light-source is daylight balanced to produce natural colors. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion height adjustment for precision control. The microscope can now be powered using an AC outlet or AA batteries. For plug-in power, the microscope uses a 5V power interface which can be used with USB chargers using the included cable. For mobile applications, you can use rechargeable batteries. P
