SOPTOP XD30M Inverted Metallurgical Microscope

Overview

The SOPTOP XD30M Inverted Metallurgical Microscope is an engineered solution for high-fidelity microstructural characterization of opaque, polished metallic and alloy specimens. Designed around an inverted optical architecture—where the objectives are positioned beneath the specimen stage and illumination is delivered from above via reflected light—the XD30M eliminates interference from specimen holders, clamps, or large sample fixtures during observation and imaging. Its optical path employs infinity-corrected, long working distance (LWD) achromatic metallurgical objectives optimized for Koehler illumination, ensuring uniform brightness, minimal chromatic aberration, and sharp contrast across the full field of view. This configuration supports routine metallographic analysis including grain size evaluation, phase distribution mapping, inclusion identification, and heat-affected zone (HAZ) assessment in both academic research laboratories and industrial quality control environments.

Key Features

• Inverted mechanical design with fixed-stage configuration, enabling stable imaging of bulky, heavy, or irregularly shaped samples—including castings, weldments, and cross-sectioned components mounted on standard metallographic mounts.
• High-eye-point wide-field plan eyepieces (PL10×/22 mm and PL15×/16 mm) provide ergonomic viewing for extended sessions and compatibility with corrective lenses; calibrated reticles and micrometers can be inserted into the eyepiece tube for quantitative linear and area measurements.
• Infinity-corrected metallurgical objective set (5×, 10×, 20×, 50×, 100× oil), featuring ultra-long working distances (up to 14.5 mm at 10×) and no cover-slip correction requirement—ideal for observing rough or coated surfaces without immersion media.
• Coaxial coarse/fine focusing mechanism with low-hand-position controls; coarse focus travel: 38 mm per revolution; fine focus resolution: 2 µm per graduation, with adjustable tension for consistent parfocal repeatability.
• Reflected-light Köhler illumination system incorporating a center-adjustable field diaphragm and variable aperture diaphragm, paired with a 12 V / 50 W imported halogen lamp and auto-ranging 90–240 V AC power supply for global laboratory deployment.
• Hinged trinocular head inclined at 45°, with interpupillary distance adjustment and diopter compensation, supporting simultaneous visual observation and high-resolution digital image capture via C-mount adapter.

Sample Compatibility & Compliance

The XD30M accommodates standard 30 mm–75 mm diameter metallographic mounts, as well as custom-sized specimens using optional extended stage plates and coaxial mechanical stage accessories. Its inverted geometry permits direct integration with hardness testers, thermal stages, and tensile fixtures for in situ correlative analysis. The system complies with ISO 9001 manufacturing protocols and conforms to IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards. When used with validated image analysis software and calibrated stage micrometers, measurement workflows support traceability under ISO/IEC 17025 and ASTM E112 (grain size), ASTM E1245 (inclusion rating), and ISO 643 (microstructure classification) guidelines.

Software & Data Management

The XD30M integrates seamlessly with SOPTOP’s proprietary image analysis suite (v5.2+), supporting real-time acquisition, multi-layer annotation, automated particle counting, grain boundary detection, and phase-area fraction quantification. Software features include audit trail logging, user access levels (administrator/operator), electronic signature capability, and export of metadata-embedded TIFF/PDF reports compliant with GLP and FDA 21 CFR Part 11 requirements when deployed on validated Windows-based workstations. Raw image data is stored in lossless 16-bit format with embedded scale calibration and objective identification tags.

Applications

• Academic metallurgy labs: Teaching microstructure evolution in ferrous/non-ferrous alloys, phase transformation kinetics, and corrosion morphology studies.
• Automotive and aerospace QC: Verification of casting integrity, weld microstructure homogeneity, and coating thickness uniformity on engine blocks or turbine blades.
• Electronics manufacturing: Inspection of solder joint intermetallic compound (IMC) formation, PCB pad plating quality, and wire bond interface defects.
• Failure analysis centers: Root cause investigation of fatigue cracks, brittle fracture surfaces, and stress corrosion cracking patterns.
• Research institutes: Correlative microscopy workflows combining optical imaging with SEM-EDS or XRD for multimodal material property correlation.

FAQ
