Suited for lab and production-line material micro-testing, this unit is a sturdy 4K Ultra HD Autofocus Metallurgical Microscope for Metal Analysis. Fitted with professional infinity-corrected optics and modular framework, it supports on-demand expansion of bright-field, polarized-light modes for testing transparent and non-transparent specimens. Reinforced anti-vibration chassis suppresses external vibration to deliver drift-free stable imaging under high magnification. Practical control layout and large workspace facilitate long-time continuous operation. Freely combinable modules avoid whole-unit replacement, bringing flexibility and cost savings for industrial-inspection and metallurgical-analysis work.
4K camera integrated with trinocular body for simultaneous eyepiece & screen viewing. Triple-output ports: HDMI, USB3.0 and WiFi for real-time ultra-HD micro-image capture.
Optical magnification 50-600 ×, max digital magnification 4560 × with four-speed objective zoom. Precision optical-path reveals tiny micro-structures of semiconductors, powders and fiber specimens.
Built-in auto-focus module delivers smooth, vibration-free focusing and improves inspection efficiency for mass-sample-testing scenarios.
Thick cast-aluminum base with balanced weight ensures zero wobble or offset during long-time slice-and-sample observation.
Minimalist white-blue research-style trinocular design, perfectly suited for university-laboratories and industrial quality-control workshops.
Widely applied in semiconductor-testing, metal-metallography, material-failure-analysis, academic-research and component-quality-inspection work.
Supports 4K photo & video recording; dual-measurement modes: on-monitor built-in measurement + PC-software-based measurement. Dual-storage via USB flash-drive and computer. Equipped with depth-of-field stacking & image-stitching functions; secondary-development supported for convenient image-archiving, comparison and advanced-data-analysis.
Binocular viewing & synchronous electronic observation: Synchronized display between eyepiece and monitor. Ordinary metallurgical microscopes only support eyepiece-only viewing; extra camera accessories are required for screen output.
Native 4K ultra-high-definition imaging + Auto-focus: Delivers 3840 × 2160 4K resolution plus hardware auto-focus for uneven-thickness specimens. Common metallurgical devices rely fully on manual focusing with lower image resolution.
Triple-output interfaces: HDMI + USB3.0 + WiFi wireless transmission. Traditional metallurgical devices mostly only have PC-USB connection without wireless-transmission capability.
Dual-measurement modes: Offline built-in measurement on-monitor plus PC-software-based measurement. Ordinary metallurgical microscopes only support PC-side measurement without hardware-embedded measuring function.
Dual-storage modes: Offline USB-flash-drive storage and PC-software-storage; saving data available with or without computer. Conventional models require PC for image-storage.
Advanced image-processing algorithm: Built-in depth-of-field stacking on-monitor plus PC-side image-stitching for uneven-height metallographic-samples. General metallurgical microscopes lack such embedded algorithm-functions.
Secondary-development supported: Multi-channel interfaces enable automation-production-line integration. General metallurgical microscopes do not support secondary-development integration.
Modular expandable optical-path: Supports adding polarized-light and other observation-modules without replacing the whole device. Ordinary digital microscopes lack dedicated metallurgical optical-path and cannot observe fine metallurgical-micro-structures.
Adopting a native 3840 × 2160 4K industrial imaging sensor, the device achieves high-fidelity restoration of microscopic morphologies such as metal-grain-structures, semiconductor-wafer-micro-textures, powder-particle-shapes and fiber-tissue-characteristics. It realizes uniform full-field imaging definition without peripheral blur or signal attenuation.
Built-in hardware auto-focus module is validated on uneven-thickness metallographic slices, semiconductor-chips and composite-material-samples. Equipped with a four-stage objective variable-magnification system, the instrument covers a total magnification range of 380-4560 ×. It satisfies dual-application-requirements: low-power macroscopic full-view scanning and ultra-high-power microscopic-microstructure fine-analysis, fully applicable to university-scientific- research, material-analysis and industrial high-precision-quality-inspection.
The embedded professional metallurgical-measurement-module supports high-accuracy dimensional-computation and real-time graphical-annotation. It integrates one-click high-definition snapshot and long-time dynamic-video-recording functions. All inspection-data and image-files support export and permanent-archiving, providing valid-data-support for academic- experimental-reports and industrial-quality-traceability-systems. Depth-of-field stacking is available both on HDMI-monitor and PC-software; image-stitching is available via PC-software.
The professional trinocular optical-tube realizes synchronous optical-eyepiece-observation and digital-monitor-display. The dual-path transmitted-and-reflected-illumination-system is compatible with opaque-metal-specimens, transparent-powder-fiber sliced-samples and semiconductor-wafer-materials. The precision XY-axis mechanical-moving-stage features ultra-smooth-transmission and high-positioning-accuracy, enabling efficient and precise-specimen-detection. Auto-focus hardware module passes long-term stability aging test before factory delivery.
Semiconductor & Microelectronics: Silicon wafers, photolithography slices, IC chips, PCB boards, FPC flexible circuits. Inspection targets: Micro chip-circuits, coating-defects, wafer-flaws, cold-solder-defects, circuit-scratches and pin-deformation; observe micron-slice-structures under max 4560 × magnification.
Metallographic Metal Specimens: Metallographic slices, steel-alloys, drill bits, milling cutters, precision-stamped-hardware. Inspection targets: Metallographic-grain-structure-analysis, heat-treatment-material-identification; detect edge-chipping, micro-cracks, burrs and abrasion-depth.
Lab Samples: Powder & Fiber: Metal-powder, chemical-powder, carbon-fiber, textile-fiber, thin-film-materials. Inspection targets: Observe particle-morphology, fiber-texture, film-delamination and micro-material-structures.
Optoelectronic & Precision-Plastic Parts: LED chips, optical-lenses, injection-molded-parts, sealing-glue. Inspection targets: Detect micro-pores, surface-stains, rough-edges, glue-bubbles & tiny cosmetic-defects.
High-Precision Miniature Components: Connectors, terminals, micro-springs, miniature-stamped-workpieces. Inspection targets: Observe tiny-gaps and crimp-flatness; perform pixel-level precise-measurement of length, hole-diameter and pitch.
Laboratory & Industrial QC Archiving: Material-research-experiments, incoming-&-finished-goods sampling-inspection; photo-&-video-archiving for defective-evidence-records and export of formal-measurement QC reports.
Optical magnification ranges 50-600 ×, max digital-magnification up to 4560 × with native 3840 × 2160 4K resolution. It clearly displays tiny-structures such as metal-grains, wafer-textures, ultra-thin-coatings and micro-cracks, ideal for high-standard-analysis of chips, new-materials and electroplated-parts.
Built-in hardware auto-focus eliminates repeated manual-focus-adjustment for uneven-thickness specimens. Greatly improves efficiency for batch-metallographic-slice-testing and multi-sample laboratory-analysis work.
Triple-output ports: HDMI, USB3.0 and WiFi. HDMI for on-site-monitor viewing; USB3.0 for high-speed PC-analysis; WiFi enables wireless casting to mobile-devices for spot-sampling-inspection and team-online-discussion.
Two-measurement-solutions: quick built-in on-monitor-measurement, high-precision professional-measurement via PC-software. Supports depth-of-field stacking (monitor + PC side) and PC-side image-stitching to generate fully-focused composite-images for uneven-height-specimens. Secondary-development-interface reserved for production-line-system-integration.
Trinocular synchronous-optical-path enables simultaneous viewing via binocular-eyepieces and 4K-monitor. Multiple-operators can check the same-micro-sample together, perfect for university-material-teaching and QC-double- re-check. Dual-storage modes: USB flash-drive local-saving and PC-batch-archiving for long-term-quality-traceability and report-generation.
