Specimen Stage: GP-L500-462H adopts large-size moving stage for large-format chips / wafers with wide travel range. Ordinary metallurgical microscopes are equipped with small-size stage only for small samples and require frequent specimen re-positioning.
Magnification Range: 380-6080X five-speed high-magnification, delivering sharp details for tiny chip-circuit inspection. Ordinary metallurgical microscopes have fewer magnification-gears and lower maximum magnification, resulting in blurry images under high power.
Imaging & Measurement: Native 4K research-grade camera, built-in on-monitor measurement, photo-video storage function. Ordinary metallurgical microscopes adopt low-definition 2K camera without onboard measurement, PC-software is mandatory for analysis work.
Application Scope: Optimized for wafers, semiconductors and large-precision-electronic-parts inspection. Ordinary metallurgical microscopes are only suitable for small metal slices and perform poorly for large chip-specimens.
Mechanics: Full-metal construction for high rigidity and vibration resistance. Hardware auto-focus module equipped. Precision coarse-fine focusing without backlash. Large-size manual XY stage with low wear and minimal clearance. Trinocular optical path maintains optical co-alignment when switching objectives.
Optics: Infinity-corrected plan-achromatic metallurgical objectives with anti-fog hard coating. Reflected-light 6V-30W halogen-lamp illumination.
Imaging and Measurement: 8.3-megapixel 4K industrial-grade CMOS camera. Multi-output interfaces: HDMI + USB3.0 + WIFI, featuring excellent anti-interference performance for industrial-environment applications. Supports both embedded on-screen measurement and PC-software-based measurement. Dual-path storage: USB flash drive and PC software. Depth-of-field stacking function is available on-screen and via PC software; the image-stitching function is supported by PC-software only. Secondary-development interface is accessible via USB3.0 / WIFI.
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.
