Stereo Zoom Microscope G208F/F1 by SDLATLAS

Overview

The SDLATLAS G208F/F1 Stereo Zoom Microscope is an ergonomically engineered optical instrument designed for high-fidelity, three-dimensional visual inspection and documentation of macro- to meso-scale specimens. Based on the Galilean optical principle with coaxial zoom optics, it delivers continuous magnification across a 1:6 zoom ratio (0.7×–4.5×) without parfocal shift—ensuring stable focus throughout the entire magnification range. Coupled with wide-field 10× eyepieces, the system achieves a total magnification range of 7×–45×, optimized for extended working distance (WD ≥ 110 mm) and large-depth-of-field observation. Its 45° inclined trinocular head supports simultaneous visual examination, photomicrography, and real-time digital imaging—making it especially suited for quality control in textile manufacturing, printed circuit board (PCB) inspection, geological sample documentation, and pre-mounting preparation in histology laboratories.

Key Features

• Galilean-type zoom optics with 1:6 continuous magnification (0.7×–4.5×), enabling seamless scaling without mechanical refocusing
• Trinocular viewing head angled at 45° for operator comfort during prolonged use; includes dedicated C-mount port (standard 1″–32 thread) for integration with industrial cameras, CMOS/CCD sensors, or DSLR adapters
• Integrated dual-illumination system: top-mounted 12 V/30 W halogen incident light for surface texture analysis and bottom-mounted transmitted light base for semi-transparent or translucent samples (e.g., woven fabrics, polymer films, thin biological sections)
• Compact R2GG modular stand with rigid aluminum alloy construction, anti-vibration damping base, and precision-machined focusing mechanism offering fine-focus adjustment (1 µm graduation) and coarse-focus travel (50 mm)
• Optical path split ratio configurable at 100:0 / 80:20 / 0:100 (eyepiece : camera), supporting concurrent visual assessment and synchronized image capture
• Compliant with ISO 10934-1 (optical microscopy — nomenclature and definitions) and aligned with ANSI Z80.10 standards for ophthalmic and general-purpose microscopes

Sample Compatibility & Compliance

The G208F/F1 accommodates specimens up to 200 mm × 150 mm in footprint, with no height restriction under the objective due to its open-frame design and long working distance. It routinely supports textile swatches (woven/knitted/nonwoven), composite laminates, solder joints, botanical sections, mineral chips, and forensic trace evidence. All optical components utilize multi-layer anti-reflective (AR) coated BK7 glass with ≥92% transmission in the 400–700 nm visible spectrum. The illumination system meets IEC 62471 photobiological safety classification for Exempt Group, and the device conforms to CE marking requirements (2014/30/EU EMC Directive and 2014/35/EU Low Voltage Directive). For regulated environments, optional audit-trail-enabled firmware upgrades support 21 CFR Part 11-compliant user access control and electronic record retention when paired with validated image acquisition software.

Software & Data Management

The microscope interfaces seamlessly with industry-standard imaging platforms—including SDLATLAS ImageStudio Pro v4.2 (Windows/Linux compatible), Olympus cellSens, and open-source alternatives such as FIJI/ImageJ via TWAIN or DirectShow drivers. Raw image capture supports TIFF (16-bit), PNG, and JPEG formats with embedded EXIF metadata (magnification, illumination mode, timestamp, operator ID). Batch annotation tools enable ROI tagging, scale bar insertion (calibrated per objective), and measurement overlays (length, angle, area) traceable to NIST-traceable stage micrometers. Exported datasets comply with ASTM E2912-22 (Standard Guide for Digital Image Capture in Microscopy) and can be ingested into LIMS or ELN systems via CSV or XML schema mapping.

Applications

• Textile QA/QC: Fiber morphology evaluation, yarn twist analysis, pilling resistance assessment, and weave defect mapping under oblique incident lighting
• Electronics manufacturing: Solder joint integrity verification (IPC-A-610 Class 2/3), component placement accuracy, and conformal coating uniformity inspection
• Materials science: Fracture surface characterization, particle dispersion analysis in composites, and corrosion pit depth profiling
• Academic research: Dissection assistance in entomology and botany, specimen curation documentation, and stereoscopic morphometric training
• Forensic labs: Toolmark comparison, fiber transfer analysis, and gunshot residue pattern documentation

FAQ

What is the maximum field of view (FOV) at lowest magnification (0.7×)?
At 0.7× with 10× eyepieces and standard 23 mm field number eyepieces, the FOV diameter is approximately 32.9 mm.
Is the transmitted light base compatible with polarized light accessories?
Yes—the base includes removable diffuser plates and accepts optional polarizer/analyzer kits (SDLATLAS PPL-Kit-F1) for stress birefringence analysis in polymers and glasses.
Can the G208F/F1 be integrated into automated production line inspection stations?
Yes—via RS-232 and USB 2.0 control interfaces, the microscope supports TTL-triggered image capture, programmable zoom positioning, and remote illumination intensity modulation through OEM SDKs.
Does the system include calibration certification?
Each unit ships with a factory-issued Certificate of Conformance (CoC) and optional NIST-traceable magnification calibration report (per ISO/IEC 17025 accredited lab).
What maintenance is required for long-term optical performance?
Annual cleaning of optical surfaces using lens-grade acetone and lint-free wipes is recommended; no internal alignment or lubrication is required under normal operating conditions (25 °C ± 5 °C, RH ≤ 60%).
