YANRUN PXS-1020 Stereo Microscope

Overview

The YANRUN PXS-1020 Stereo Microscope is a high-stability, dual-eye inverted-angle stereoscopic optical instrument engineered for routine inspection, quality control, assembly verification, and educational microscopy applications. It operates on the principle of Greenough optical design—employing two separate optical paths with angled objectives—to deliver true three-dimensional depth perception and natural parallax, essential for precise manual manipulation under magnification. Unlike compound microscopes optimized for thin-sectioned biological specimens, the PXS-1020 is purpose-built for low-magnification observation of opaque, reflective, or bulky samples—including electronic components, mechanical parts, printed circuit boards, mineral specimens, botanical samples, and forensic evidence—without requiring sectioning or staining. Its fixed 1× and 2× objective pair provides a calibrated magnification range of 10× to 20× when combined with standard WF10× eyepieces, ensuring consistent scale fidelity across daily use in industrial and academic settings.

Key Features

• Dual-path Greenough optics delivering uncorrected but highly intuitive stereoscopic imaging with minimal chromatic aberration at low magnifications
• Hinge-mounted binocular head with 45° inclination and full 360° rotation, enabling ergonomic positioning for extended observation sessions
• Interpupillary distance adjustment (55–75 mm) accommodates a wide range of users, supporting long-term visual comfort and alignment accuracy
• Rack-and-pinion coarse focusing mechanism with integrated travel limiter and torque-adjustable focusing knob—designed for repeatable, vibration-resistant operation during manual handling tasks
• Modular illumination system: Standard 6 V / 20 W halogen upper light source ensures uniform coaxial illumination; optional lower-light configurations support transmitted-light contrast enhancement for semi-transparent specimens
• Reversible 75 mm stage featuring both matte black/white contrast plates and a frosted glass diffuser—optimized for variable reflectivity and edge definition across diverse sample types

Sample Compatibility & Compliance

The PXS-1020 accommodates specimens up to 90 mm in height beneath the objective, making it suitable for large-volume industrial parts, soldered assemblies, geological hand samples, and prepared entomological mounts. Its open-stage architecture allows direct access for tweezers, probes, or micro-manipulators without obstruction. While not certified for ISO 17025-accredited calibration laboratories or GLP/GMP-regulated environments as a standalone metrology tool, the microscope’s mechanical repeatability and stable optical alignment meet baseline requirements for internal QC documentation per ISO 9001 Clause 7.6 (Control of Monitoring and Measuring Resources). All electrical components comply with IEC 61010-1 safety standards for laboratory equipment. No hazardous substances are used in construction per RoHS Directive 2011/65/EU.

Software & Data Management

The PXS-1020 is an analog optical platform with no built-in digital imaging or software interface. However, it features standardized 23.2 mm photo-tube threading compatible with third-party C-mount adapters (e.g., Thorlabs, Edmund Optics), enabling integration with USB3/UVC-compliant CMOS cameras (e.g., FLIR Blackfly S, Basler ace) and industry-standard image acquisition software such as Ocular, Stream Motion, or MicroManager. When paired with calibrated stage micrometers and NIST-traceable reference standards, image-based measurement workflows can be validated for internal traceability. Audit trails, metadata logging, and user-access controls must be implemented externally via host PC systems compliant with FDA 21 CFR Part 11 if deployed in regulated manufacturing environments.

Applications

• Electronics manufacturing: Visual inspection of solder joints, component placement, PCB trace continuity, and rework verification
• Mechanical QA: Surface defect identification (scratches, burrs, porosity), thread pitch assessment, and fastener alignment checks
• Materials science education: Macrostructural analysis of alloys, polymers, and composites; fracture surface characterization
• Life sciences: Dissection support, arthropod morphology studies, seed germination monitoring, and mycological specimen survey
• Forensic document examination: Ink differentiation, paper fiber analysis, and indented writing recovery
• Jewelry and watchmaking: Gemstone setting verification, gear train inspection, and finish quality evaluation

FAQ

Is the PXS-1020 compatible with digital camera attachments?
Yes—via its standard 23.2 mm photo-port, using commercially available C-mount or trinocular adapters.
Can the working distance be extended beyond 90 mm?
No—the mechanical design fixes the objective-to-stage clearance at 90 mm; auxiliary long-working-distance objectives are not supported.
Does the microscope include eyepiece reticles or stage micrometers?
No—these are optional accessories and must be ordered separately.
What is the expected service life of the halogen illumination module?
Rated for approximately 1,000 hours at nominal voltage; lifetime decreases significantly with overvoltage or frequent thermal cycling.
Is technical support available in English for international customers?
Yes—YANRUN provides English-language documentation, firmware updates (where applicable), and remote diagnostic assistance through authorized regional distributors.
