Description

GHEXA-15.2601-R-T

GHEXA-15.2601-R-T is a professional trinocular reflected-light polarizing microscope engineered for advanced materials analysis and petrographic studies. Featuring wide-field WF10x/20mm eyepieces (including one with crosshair reticle), a quintuple centerable nosepiece, long-working-distance infinity-corrected strain-free plan objectives (5x, 10x, 20x, 50x), a large 148 mm diameter rotatable round stage, full set of compensators (1λ full-wave plate, 1/4λ quarter-wave plate, quartz wedge), and powerful 5W reflected LED polarization illumination, this model delivers exceptional image contrast, precise birefringence observation, and reliable performance for routine and research-grade polarized light microscopy in geology, metallurgy, polymers, forensics, and industrial quality control laboratories.

Key Applications & Uses

• Petrographic and mineralogical analysis — Identification of minerals, rock thin sections, ore characterization, and determination of optical properties (birefringence, extinction angle, sign of elongation) in geology and earth sciences departments.
• Metallographic examination — Inspection of grain structure, inclusions, phase identification, and stress/strain analysis in steels, alloys, welds, and heat-treated metals for materials science and failure analysis labs.
• Polymer and composite material studies — Observation of crystalline structures, orientation, residual stresses, and filler distribution in plastics, resins, fibers, and advanced composites.
• Forensic science applications — Analysis of fibers, paints, glass fragments, soil particles, and unknown crystalline materials using polarized light contrast techniques.
• Industrial quality control & R&D — Evaluation of pharmaceuticals (crystal habit), semiconductors, ceramics, thin films, coatings, and abrasives in pharma, biotech, electronics, and manufacturing sectors.
• Digital documentation and teaching — Trinocular port enables attachment of cameras for live imaging, measurement, and archiving of interference colors and anisotropic features.

Why Choose from G-Hexa?

• True infinity-corrected strain-free optics — Delivers flat, high-contrast, aberration-free images across the field with long working distance objectives, minimizing stress-induced artifacts in polarized observations.

Frequently Asked Questions (FAQs)

Q: Is GHEXA-15.2601-R-T suitable for transmitted light polarization as well? A: This model is configured for reflected light polarization only (ideal for opaque samples like metals, minerals in polished sections, and polymers). For transmitted light applications (thin sections), consider our dual transmitted/reflected models or dedicated petrographic series.

Q: What is the purpose of the crosshair reticle eyepiece? A: The WF10x/20mm reticle eyepiece with crosshairs is used for precise centering of grains, measuring extinction angles, determining cleavage directions, and aligning the specimen during conoscopic observation.

Q: Can I attach a digital camera to this microscope? A: Yes — the trinocular head includes a dedicated vertical phototube with C-mount compatibility (adapter may be required depending on camera model). Contact G-Hexa for recommended camera options.

Q: How do the compensators help in observation? A: The 1λ tint plate enhances color contrast for low birefringence, the 1/4λ plate enables distinction of fast/slow rays, and the quartz wedge allows precise measurement of retardation and birefringence order.

Q: Is the stage large enough for standard petrographic slides? A: The 148 mm rotatable round stage easily accommodates standard 28×48 mm or 30×45 mm petrographic thin sections and polished mounts, with clips for secure holding.

Q: What maintenance is required for the LED illumination? A: The 5W LED is maintenance-free with an extremely long service life. No lamp replacement is typically needed for years of regular laboratory use; intensity is adjustable via the built-in controller.
