AmScope B490 Compound Binocular Microscope, WF10x Eyepieces, 40X-1000X Magnification, Brightfield, Halogen Illumination, Abbe Condenser, Double-Layer Mechanical Stage, Sliding Head, High-Resolution Optics, Anti-Mold

Compound microscope provides high magnification for biological use and educational applications
Binocular viewing head with pair of 10x widefield eyepieces and sliding head with 55 to 75mm interpupillary adjustment, fixed 30-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing
Forward-facing nosepiece with 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic precision-ground optical-glass objectives that provide color correction of magnified images, and anti-mold surfaces to preserve optics in high-humidity areas
Brightfield, halogen illumination with rheostat to control light intensity, and 1.25 NA Abbe condenser with iris diaphragm and rack-and-pinion focus control for precise focus, clear examination, and light control
Double-layer mechanical stage with 1.0mm stage divisions and stage stop; and graduated coarse and fine focus with tension control to prevent stage drift
