Zuzi Polarising Metallurgical Microscope, Model 146MET: Optical Precision for Birefringent Materials and Structures
The Zuzi Model 146 is a professional polarising metallurgical microscope, designed for observations under polarised light. Its infinity-corrected optics, combined with a robust and stable mechanical system, make it an essential tool for applications in petrography, mineralogy, metallurgy, materials science, histology and pathological anatomy.
Polarised Light Observation
The polarisation system includes a polarising filter (north-south axis) located below the stage and an analyser (east-west axis) above it. When both filters are positioned orthogonally (90°), light is extinguished, resulting in a dark background. If the sample exhibits birefringence, relevant structures appear bright against this background, allowing clear observation of crystals, pigments, anisotropic liquids or amyloid deposits.
Advanced Optics and Köhler Illumination
The microscope features infinity-corrected optics and a Köhler illumination system with field and aperture diaphragms, adjustable Abbe condenser (NA 1.25), pre-condenser and fine intensity control via a 30 W halogen lamp. This setup ensures uniform, distortion-free illumination with high contrast.
Complete Polarimetry System
It includes a 360° rotatable polariser, a rotating analyser with Vernier scale (90°), and a slidable Bertrand lens for conoscopic observation. There is also a slot for compensator plates: gypsum, mica and quartz wedge, all positioned at 45° to the principal vibration axes.
High-Precision Rotating Stage
The 160 mm circular stage rotates 360° with 0.1° graduation, features a locking mechanism, and allows for the addition of a mechanical stage for precise sample movement. Fixed clips ensure secure sample placement.
Ergonomic Design and Intuitive Controls
The Siedentopf-type trinocular head is inclined at 30°, with interpupillary distance adjustment (55–75 mm) and dioptre correction on the left eyepiece holder. Compatible with Zuzi ocular cameras. The coaxial coarse and fine focusing knobs are ergonomically positioned: the right one with friction control, the left with a locking lever to protect the sample.
Dual Illumination: Episcopic and Diascopic
The episcopic (reflected) illumination system includes a 12 V / 30 W halogen lamp, centreable diaphragms, a rotating filter holder (green, blue, yellow, polariser) and full control of the incident light. The diascopic (transmitted) illumination system uses a second halogen lamp of the same type, with a height-adjustable Abbe condenser, movable filter holder, and precision diaphragms.
Advanced Applications in Industrial Microscopy
The Model 146 is designed for demanding analyses in metallography, microcircuit observation, crystalline materials, anisotropic liquids, thin films, PCB and more. Its T-shaped architecture ensures maximum stability without compromising ergonomics, making it a versatile solution for quality control labs, teaching and technical analysis.
