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. The dedicated photo port allows for simultaneous viewing and imaging. Features: An advanced metallurgical microscopy system with reflected illumination Polarized lighting for structural analysis Includes a range of filters for lighting manipulation 5X, 10X, and 50X long-working-distance metallurgy objectives Co-axial coarse & fine focusing system 30 degree inclined 360 degree rotatable trinocular head 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
