GP-L400-462H is built to handle complex material-analysis workflows and functions as a dependable Material testing metallographic microscope with 4K Ultra HD & Autofocus. Precision infinity-corrected optical components produce crisp, color-accurate visuals for detailed sample review. Scalable modular construction makes it simple to integrate bright-field and polarized-light observation features as project needs evolve. A heavy-duty base absorbs external vibration, keeping images stable even at elevated magnification. Users can reconfigure individual modules instead of replacing the whole device to fit varied testing scenarios. Optimized operation and generous workspace help shorten inspection cycles for industrial quality checks and metallurgical assessment.
This Autofocus 4K Ultra HD Metallurgical Microscope for Material Testing is suitable for microscopic observation of metallographic microstructures and surface morphology. It serves as an ideal research tool for metallurgy, mineralogy and precision-engineering disciplines.
Built-in 4K camera matches trinocular head for synchronous viewing via eyepiece and monitor. Multi-output ports (HDMI, USB3.0, WIFI) transmit ultra-HD micro-images in real-time.
50-500× optical magnification; maximum digital magnification reaches 2000×. Multi-layer precision lens path delivers crisp images for micro-detail inspection.
Hardware auto-focus module realizes smooth, vibration-free focusing and boosts efficiency for mass-sample testing.
Balanced heavy-duty metal base keeps the microscope steady during long-hour continuous observation.
Perfect for industrial inspection, metallographic analysis, material research, university teaching and quality evaluation.
Supports 4K photo & video recording, dual-measurement modes (on-screen built-in + PC-software). Dual-storage via U-disk & computer. Depth-of-field synthesis runs both on-monitor and PC-software; image-stitching is available only in PC-software. Secondary-development is supported for image archiving, comparison and advanced analysis.
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.
4K ultra-HD imaging: 3840×2160 resolution reproduces fine microstructure details of grains and coatings. Conventional metallurgical cameras mostly deliver 1080P resolution with limited resolving power.
Hardware auto-focus function: Auto-focus improves inspection efficiency. Ordinary metallurgical microscopes adopt fully manual focusing.
Multi-interface output: HDMI + USB3.0 + WIFI for monitor, PC and wireless transmission. Traditional metallurgical equipment offers limited interfaces without WIFI capability.
Dual-measurement modes: Offline built-in measurement on-monitor plus PC-software measurement. Ordinary metallurgical microscopes only support PC-side software measurement.
Dual-storage modes: Offline U-disk storage and PC-software storage, data saving available with or without connected computer. Conventional models require PC connection for image saving.
Advanced image algorithms: Depth-of-field synthesis and image-stitching solve partial blurring caused by height-difference samples. Ordinary metallurgical microscopes lack these algorithm-driven functions.
Secondary-development supported: Ready for automatic-system integration. General metallurgical microscopes do not support secondary-development capability.
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. Hardware auto-focus module fitted. Precision coarse-fine focusing without 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 & Measurement: 4K industrial CMOS camera (3840×2160 resolution). Multi-output interfaces: HDMI+USB3.0+WIFI, good anti-interference performance for industrial-environment use. Supports embedded on-monitor measurement and PC-software measurement. Dual-path storage via U-disk and PC-software.
Operating Environment: Working temperature 10-35℃, relative humidity 30-75%RH. Stable under regular factory electromagnetic-environment. Avoid heavy vibration, corrosive gas and heavy dust. Keep WIFI module away from strong signal-interference sources.
Quality & Maintenance: Full-item factory inspection. Do not disassemble optical modules or auto-focus module. Regular dust-proof cleaning will 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.
4K-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×. Equipped with native 3840*2160 4K camera. It clearly captures metallographic grains, tiny electroplating defects and PCB traces. Ideal for high-standard incoming QC for machinery, electroplating and electronic-component industries.
Built-in hardware auto-focus eliminates repeated manual focusing on specimens with uneven surfaces, greatly cutting operation time during continuous batch testing. Well-suited for all-day production-line re-checking and high-volume-sample laboratory analysis.
Two measurement modes: fast built-in measurement on-monitor, high-precision measurement via PC-software. Depth-of-field synthesis and image-stitching functions produce fully-focused panoramic pictures. Secondary-development function is available.
Trinocular synchronous optical-path enables simultaneous observation via eyepieces and 4K-monitor for group defect review. Dual-storage via U-disk and PC-software archives all 4K images and measurement reports, satisfying university-lab teaching, factory-quality-traceability and scientific-report-filing requirements.
Neutral-packing shipment is available upon request.
