GP-L200-300C is a High magnification metallographic microscope. High Magnification Metallurgical Microscope enables simultaneous observation with binocular eyepieces and external display. Built-in bright-field and dark-field modes with uniform coaxial vertical illumination, it faithfully reproduces micro-structures such as metal grains, coatings and cracks. It supports image capture, photo archiving and dimension measurement & analysis. Featuring solid build, simple operation and expandable modular design, it is ideal for industrial quality inspection, material metallurgical analysis, failure analysis, teaching and scientific research.
High-definition camera integrated with trinocular metallurgical frame, enabling simultaneous eyepiece viewing and digital-screen observation via HDMI output for real-time micro-image capture.
50-500 × optical magnification, max 2000 × digital magnification. Equipped with professional metallurgical objective lenses for transparent, delicate imaging to observe micro-metal structures.
Coaxial coarse-and-fine focusing mechanism delivers smooth, stable focusing and effectively reduces image vibration.
One-piece cast-aluminum base offers solid load-bearing, keeping the microscope stable and free of shifting during long-time metallurgical-slice inspection.
Classic white-and-blue lab-style body with standard trinocular metallurgical layout, clean and professional for laboratories and quality workshops.
Ideal for metal-metallographic analysis, wafer-slice inspection, material-testing, university-research and component-failure-analysis work.
Built-in precision-measurement function, supports 1080P photo/video capture and USB-flash-drive storage. Digital images are easy to archive, compare and analyze in post-processing.
Binocular viewing & synchronous electronic observation: Real-time synchronization between eyepiece and monitor display. Ordinary metallurgical microscopes mostly support eyepiece-only observation; extra camera accessories are required for screen output.
Wide magnification range: Up to 500 × optical magnification and 2000 × electronic magnification for microstructure observation. Conventional models have limited electronic-zoom capability.
HDMI direct output: Directly connect to monitor via HDMI. General metallurgical microscopes need additional camera and capture card for video output.
Built-in offline measurement: Dimension measurement directly on-monitor. Ordinary metallurgical microscopes only support PC-based measurement without hardware-embedded measuring function.
Offline USB-flash-drive storage: Capture photos and videos to USB flash drive without computer. Traditional models require PC for image saving.
Dedicated metallurgical optical path: Optimized for analysis of metal, coating and grain-structure. Ordinary digital microscopes lack metallurgical optical system and cannot observe metallurgical micro-structures.
Adopting a native 1920 × 1080 Full-HD industrial camera, the microscope is fully calibrated with standard metallurgical-test specimens. It clearly captures grain boundaries, coating delamination, micro-cracks and material metallographic-structures, delivering consistent sharp details across the entire field-of-view.
Equipped with multiple achromatic metallurgical objectives for high-precision high-magnification microscopic detection. The professional trinocular design enables synchronous dual observation via eyepieces and external monitors, perfectly suited for metal-material analysis, coating-thickness inspection, grain-rating and various professional metallurgical-testing scenarios.
The built-in professional-measurement system overlays real-time dimensional data on the display screen. It delivers accurate measurement of core metallurgical indicators including coating thickness, grain length, crack width and delamination spacing, and supports real-time annotation, image archiving and test-data export.
Built with transmitted-and-reflected dual-path lighting, compatible with opaque-metal specimens and transparent-inlaid specimens. The precision High Magnification Metallurgical Microscope stage features smooth XY-axis movement for fast and accurate area positioning. The full-metal heavy-duty body guarantees stable, jitter-free operation during long-duration industrial-material detection.
Semiconductor & Electronic Components: IC chips, silicon wafers, photolithography slices, PCB boards, FPC flexible boards, solder joints, pins. Inspection targets: Observe internal chip circuits, wafer coatings, cold-solder defects, oxidation, circuit scratches and pin deformation; analyze micro-slice structures under max 2000 × magnification.
Metal Materials & Metallographic Specimens: Metallographic slices, drill bits, milling cutters, stamped-metal hardware. Inspection targets: Metallographic-grain-structure analysis, heat-treatment-material identification; detect edge-chipping, micro-cracks, burrs and abrasion depth.
LED Optoelectronic & Plastic-Molded Parts: LED chips, optical-plastic parts, injection & die-cut products. Inspection targets: Inspect tiny notches, surface stains, rough edges, micro-foreign particles, glue-delamination and sealing micro-defects.
High-Precision Miniature Components: Connectors, terminals, micro-springs, tiny 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: Metallographic-slice-experiment analysis, incoming-&-finished-goods sampling-inspection; photo-&-video archiving for defective-evidence records and export of formal-measurement QC reports.
Max 500 × optical magnification and 2000 × digital magnification. Suitable for micro-analysis of metal-metallographic-structures, wafers, coatings and powder-materials for material-labs and semiconductor-incoming-inspection.
Trinocular synchronous optical-path: observe samples with binocular eyepieces while outputting images to monitor via HDMI. Supports multi-person simultaneous viewing for training, discussion and double-check of defects.
Built-in precision-measurement function with direct HDMI display. Capture Full-HD photos and videos saved directly to USB flash drive. Complete measurement and image-archiving on-site with simple workstation layout.
Standard metallurgical stage with multiple objective-lenses, compatible with metal-samples, PCB-coatings, semiconductor-chips and micro-slices. Widely used in material-labs, hardware-coating-testing, university-research and electronic-chip QC.
Precision coarse-and-fine manual-focusing avoids image-shifting. Solid stable body for long-time lab-testing. Integrated Full-HD viewing, photo-and-video-recording for routine-micro-analysis and mass-sample-re-inspection.
