Binocular Stereozoom Microscope with Brightfield and Darkfield Illumination for Gemology

This binocular stereozoom microscope is engineered for gemological applications, combining versatile observation modes and precise optics critical for gemstone analysis and biotechnology-related microscopy. It features:

• Observation Modes: Brightfield and darkfield for enhanced contrast and detail in gemstone examination.
• Optical System: Binocular 45° inclined head with 360° rotation, adjustable interpupillary distance (51–75 mm), and dioptric adjustment on both eyepieces. Comes with WF10x/21 mm high eye-point eyepieces.
• Zoom Capability: Parfocal achromatic zoom objective with 0.7x to 4.5x magnification (zoom factor 6.43:1), enabling detailed stereoscopic imaging at a working distance of 100 mm.
• Specimen Stage: Specialized gemological stage equipped with a clamp for secure handling of gemstones during observation.
• Focusing Mechanism: Rack and pinion controlled by dual knobs for precise focusing essential in molecular diagnostics and bioprocessing workflows involving small samples.
• Illumination Systems:
• Darkfield Illumination: Advanced side-emitting LED ring with a 38° emission angle and adjustable brightness to highlight surface features and inclusions.
• Transmitted Light: LED illuminator beneath the stage with adjustable brightness, supporting detailed internal structure analysis.
• Incident Illumination: Flexible gooseneck arm with 4 LEDs, each with brightness control, suitable for surface examination of gems or biological specimens.
• Stand: Fixed arm stand with tilt and position lock, capable of full overturn and rotation to facilitate observation of water-immersed specimens, which is critical in bioimaging and synthetic biology sample preparations.
• Color Temperature: Pure white LED illumination at 6300 K optimizes color fidelity during analysis, important in molecular biology and biomanufacturing quality control.

This binocular stereozoom microscope is widely adopted in biotechnology and molecular diagnostics for its flexibility in *live-cell imaging*, *fluorescence analysis*, and *bioprocessing quality assessments* while being indispensable in advanced gemological research and biomedicine. It supports detailed stereoscopic visualization critical for biopharmaceutical production pipelines and synthetic biology research workflows.
