Built for professional material research and quality control, this Metallurgical Microscope for Material Testing uses premium infinity-corrected optics and flexible modular construction for sharp, true-to-color imaging. System upgrades support bright-field and simple polarized-light observation. The heavy rigid stand suppresses vibration and image shifting under high magnification. Ergonomic mechanics ease fatigue for extended work sessions, and the large-format stage accepts large-dimension samples. Modular interchangeable parts allow custom configuration without full-unit replacement. Suited for professional-level metallography and industrial inspection, it performs well in laboratories and on production floors.
This Metallurgical Microscope for Material Testing is suitable for the microscopic observation of metallographic microstructures and surface morphology, making it an ideal tool for research in metallurgy, mineralogy, and precision engineering.
HD camera built-into trinocular frame; simultaneous observation via eyepiece and HDMI monitor. Real-time micro-image output over HDMI.
Multi-layer precision optical-path delivers sharp details for fine-feature inspection.
Stable coaxial focus knobs paired with lens-barrel assembly ensure steady focusing and minimize image shaking.
Integrated heavy-metal base with balanced weight distribution, keeping the whole instrument stable without wobble during extended sample observation.
Minimalist white-and-blue trinocular styling with premium visual texture, matching lab environments and quality-inspection workstations.
Applicable for industrial-part inspection, metal metallographic analysis, material-structure observation, university teaching-research and material-quality evaluation.
Digital imaging simplifies file archiving, image-comparison and post-analysis workflows.
Binocular viewing plus synchronous electronic observation: Eyepiece view and monitor display work synchronously. Ordinary metallurgical microscopes only support eyepiece observation; extra camera accessories are required for screen output.
Wide magnification range: Visual magnification up to 500× and electronic magnification up to 2000× for microstructure study. Conventional metallurgical microscopes have limited electronic zoom capacity.
Direct HDMI output: Connect directly to a monitor via HDMI cable. General metallurgical microscopes require separate cameras and capture cards for image output.
On-monitor offline measurement: Complete dimension measurement directly on the connected monitor; no PC required. Ordinary metallurgical microscopes rely exclusively on PC-based measurement software.
Offline U-disk storage: Save photos and videos onto a U-disk without a computer. Traditional models must connect to a PC for image saving.
Dedicated metallurgical optical path: Optimized for metal-grain, coating and metallographic-material analysis. Ordinary digital microscopes lack this specialized optical path and cannot visualize metallographic structures.
Mechanics: Full-metal construction for high rigidity and vibration resistance. Precision coarse-fine focusing with zero backlash. Manual XY stage with low wear and minimal clearance. Trinocular optical path maintains optical co-alignment during magnification switching.
Optics: Infinity-corrected plan-achromatic metallurgical objectives with anti-fog hard coating. Separated coaxial LED illumination.
Imaging and Measurement: 2-Megapixel HD CMOS Sensor (1920×1080 Resolution). HDMI-only video output. Measurement operations are implemented via embedded display firmware. Pre-calibrated at the factory; parameters are retained after power-off; no daily calibration required. Data can only be saved to a USB flash drive.
Operating Environment: Working temperature 10-35℃, relative humidity 30-75%RH. Stable under regular factory electromagnetic conditions. Avoid heavy vibration, corrosive gas and heavy dust.
Quality & Maintenance: Full-item factory inspection. Do not disassemble optical modules. Conduct regular dust-proof cleaning to extend service life.
Semiconductor & Microelectronics:
Silicon wafers, lithography slices, IC chips, PCBs, FPC flexible circuits.
Inspection targets: micro chip circuits, coating defects, wafer flaws, cold-soldering joints, circuit scratches, pin
deformation.
Metallographic Metal Specimens:
Metal sections, steel, alloys, precision stamped hardware.
Inspection targets: metallographic grain structures, heat-treatment evaluation, micro-cracks, edge chipping, burrs,
wear traces and material impurities.
Laboratory Powder & Fiber Samples:
Metal powder, chemical powder, carbon fiber, textile fiber, thin-film materials.
Observe particle morphology, fiber texture, film delamination and micro-scale material structures.
Optoelectronic & Precision Plastic Components:
LED chips, optical lenses, injection-molded parts, sealing adhesives.
Detect micro-pores, surface stains, rough edges, delamination, bubbles and tiny cosmetic defects.
High-Precision Miniature Components:
Connectors, terminals, micro-springs, micro-stamped work-pieces.
Pixel-level accurate measurement for gaps, hole diameters and pitch dimensions.
Laboratory & Industrial Quality-Control Workflow:
Material-research experiments, incoming-goods and finished-product sampling inspection. Photo/video archiving and
QC-report export.
Optical magnification: 50-500×; electronic magnification: 200-2000×. This magnification range covers metallographic grain structures, electroplated coatings and PCB surface conditions. Well-suited for factory incoming inspection and daily analysis within small-to-medium-size material laboratories.
Trinocular optical-path enables synchronous viewing from binocular eyepieces and HDMI-display. Inspectors or instructors can review sample defects together. Perfect for production-line double-checking and basic university-laboratory training activities.
Single-HDMI output with built-in on-monitor measurement; no computer required. 1080P photos and videos save directly onto compatible U-disk. Plug-and-play installation fits low-cost production QC stations and compact laboratories.
Upgraded high-rigidity stand together with manual coarse-fine focusing. Smooth focusing performance plus anti-vibration capability eliminate image shifting. Durable for high-volume daily sample testing and long-time static-sample observation.
Standard metallurgical stage plus full set of objective lenses support steel specimens, hardware coatings, electronic components, mineral slices and conductive thin-films. Widely deployed in electroplating plants, machinery workshops and university basic-material-research labs.
