This is a feature-packed economical metallurgical microscope with an upright design and 30W polarized-light episcopic illumination. The plan-achromatic optical system offers sharp flat-field images with excellent color-correction across three magnification levels: 50X 100X 500X. The Siedentopf head with dual diopters and high-eyepoint eyepieces provide a comfortable and adjustable viewing platform. Features: An advanced metallurgical microscopy system with reflected illumination Polarized lighting for structural analysis Includes a range of filters for light magnification 5X 10X and 50X long-working-distance metallurgy objectives 10X plan eyepieces for flat-field viewing Co-axial coarse & fine focusing system 30 degree inclined 360 degree rotatable binocular head Full optical glass elements Precise ground glass lens All metal mechanical parts Coaxial coarse and fine focusing Dual focusing control knobs Focusing tension control mechanism Adjustable interpupillary distance Adjustable diopters on both eye tubes Solid metal frame construction with stain resistant enamel finish Manufactured under ISO 9001 quality control standards Excellent five (5) year factory warranty Specifications: Head: 30 degree inclined binocular Eyepieces: High-eyepoint WF10X/18 Interpupillary Adjustment: Siedentopf Nosepiece: forward quadruple RMS thread Tube length: 160mm Objectives: 5X/0.13 10X/0.25 50X/0.6 long-working-distance plan achromatic Polarization System: removable analyzer/polarizer filters for episcopic lighting with +/- 25° adjustment Focus System: coaxial coarse/fine focus Focus Travel Range: 28mm Fine-focus Precision: 0.002mm Stage: 140x132mm double layer mechanical stage Stage X-Y Movement: 75x50mm Packing List : One ME580 microscope with binocular Siedentopf head Three LM Plan objectives (5X 10X 50X) One pair of PL10X18 eyepieces One Halogen episcopic illuminator module Two halogen lamp bulbs Six filters (polarizer analyzer green blue yellow diffuser One AC cord One pack of lens tissues One dust cover One tension wrench One instruction booklet
