Unlike most other metallurgical microscopes, this model comes with both reflected (EPI) and transmitted illuminations as well as a 1.3MP true color digital image camera. It is an ideal instrument for metallurgical, mineral and crystal identification. Features: High quality trinocular professional upright metallurgical metallographic microscope with reflected and transmitted illumination systemPerfect for detail examination and micro-analysis of surface structures of metallic materialsExcellent for quality control in industrial and research applications including metallurgical labs, silicon wafer inspection, and foundriesEight total magnification settings: 40X, 80X, 100X, 200X, 400X, 800X, 1000X and 2000X30 inclined 360 rotatable sliding trinocular headFully coated optical system with high resolution23mm universal/standard photo portAdjustable interpupillary distanceAdjustable diopters on both eye tubesFour superior quality PLAN DIN objectives, 4X, 10X, 40X (spring), and 100X (spring)Two pairs of widefield eyepieces, 10X and 20XAdvanced EPI-illumination design offers excellent halogen illumination and optimal image clarityEpi-Illumination has independent filter holders, aperture/field diaphragms and diaphragm alignment controlsBrightfield transmitted lighting system has 1.25 (N.A.)
