Belonging to the high-definition intelligent-inspection product lineup, the GP-462H-4K Autofocus Digital Microscope is a full-featured auto-focus digital microscope. Upgraded with cutting-edge hardware and software optimizations, it delivers true-to-life color rendering, fast response and highly-detailed imaging. Its built-in auto-focus system eliminates tedious manual focusing while sustaining high focusing precision. When samples shift or working-distance conditions change, the unit automatically detects image blurring and triggers auto-refocusing. It keeps targets within the focus frame sharply rendered in real-time and allows flexible working-distance adjustment. Fast, accurate focusing paired with intuitive controls reduces the learning curve for all operators. An external USB interface supports convenient storage of snapshots and video recordings.
Camera module integrated with the microscope main unit; outputs real-time 4K ultra-HD imagery with a built-in measurement system. Supports HDMI, USB and WiFi multi-output for synchronous observation, measurement and recording workflows.
Precision multi-layer lens optical path captures sharp, detailed images to satisfy high-precision inspection requirements for tiny workpieces.
Built-in auto-focus module enables smooth, stable focusing, reduces image shake and eliminates repetitive manual-focus operations.
Wide square metal base paired with stainless-steel support pole keeps the instrument stable and free of wobble during long-hour inspection work.
Rugged metal body with blue-black color scheme and minimalist vertical design, combining technical aesthetics and premium-grade industrial texture.
Standard ring-light source provides even, glare-free illumination. Widely deployed for industrial inspection, electronics repair, teaching-research, material-quality testing and sample-analysis tasks.
4K digital CCD imaging upgrades traditional visual observation. Images can be transmitted via wired or wireless connection for storage, comparison and post-processing through supporting software.
Electronics Industry: PCB boards, FPC flexible circuits, solder joints, pins and IC chips; inspect cold-solder defects, oxidation, surface scratches and bent pins.
Hardware & Cutting Tools: Drill bits, milling cutters and precision-metal parts; check cutting-edge chipping, surface scratches, burrs, abrasion and surface micro-cracks.
LED & Plastic-Molding Components: LED dies, plastic-molded and die-cut products; detect notches, stains, rough edges and tiny foreign-particle contamination.
Precision Miniature Parts: Connectors, terminals and tiny springs; observe micro assembly gaps and crimp quality; perform pixel-level length-and-pitch measurement.
Calibrated with standard-resolution test targets; sharpness of both image center and edge is fully recorded. It delivers native 4K ultra-HD picture quality, clearly restores fine workpiece textures and supports smooth real-time imaging at 60 fps.
Auto-focus response speed and stability are validated on PCB, metal, plastic and uneven-surface workpieces. The built-in depth-of-field stacking function automatically merges multiple focused image layers to resolve blurring caused by large-height-difference samples and achieve fully-sharp composite output.
Under stable laboratory conditions, the same workpiece feature is measured 10 consecutive times with minimal reading fluctuation. Equipped with a built-in professional-measurement system; supports length, angle, radius, area and other dimensional inspections to meet industrial-precision-inspection requirements.
Simultaneously equipped with three output modes: HDMI + USB3.0 + WiFi. HDMI connects to a monitor for instant on-site viewing; USB3.0 links to PC for software-based measurement, image capture and data storage; WiFi wireless transmission supports real-time preview on mobile phones or tablets for flexible multi-scenario workflows.
Comes with a dimmable LED ring-light source providing multi-angle uniform fill-light, effectively eliminating shadows and reflections on metallic and glossy parts. The thickened-base stable lifting stand maintains stable performance during long-duration inspection.
Original real-world shots of PCB circuits, BGA solder joints, electronic terminals and mold micro-cracks can be provided on-demand for quality-inspection and measurement reference.
4K ultra-HD imaging: 4K output delivers rich image detail. Most ordinary digital microscopes only provide 1080P with limited resolution performance.
Auto-focus function: Auto-focus improves inspection efficiency and enables hands-free operation. Conventional digital microscopes rely entirely on manual focusing.
Multi-mode output: HDMI + USB3.0 + WiFi; compatible with monitors, PCs and mobile devices. Common competing models are limited to single-USB interfaces.
Advanced image algorithm: Depth-of-field stacking optimizes imaging for samples with large height differences. Ordinary microscopes offer no such advanced image-processing capability.
Rugged industrial stand & base: Rigid mechanical-structure for continuous production-line inspection. General-purpose microscopes use lightweight brackets with poor stability.

A1:
First clean the lens with dust-free cloth to remove dust, fingerprints and oil stains. Confirm auto-focus function
is
enabled and adjust working-distance between workpiece and lens. For workpieces with large height-difference,
activate
depth-of-field stacking for full-area sharp imaging. Prevent strong ambient light from shining directly onto lens,
which will cause focusing failure and blurry output.
A2:
Reasonable shooting-layer quantity and step distance need to be configured according to actual workpiece
height-difference. Insufficient image layers or excessive step distance will result in incomplete composite output.
Workpiece vibration during capture will also lead to composite dislocation and local blurring.
A3:
Check PC storage permissions and saving-file-path (avoid Chinese characters and special symbols within path
strings).
Restart software and hardware device, re-establish USB connection. Re-install official supporting-software package
in
case of software anomalies.
