Complete Microscope System - Spring Model

Execute high-precision micro-pavé gemstone setting, fine hand engraving, and detailed jewelry inspection with optical clarity and ergonomic comfort. The Professional Jewelry Stereo Microscope System (Spring Arm Model) features a binocular continuous zoom optical head (7X–45X) paired with a 0.5X Barlow objective lens that provides an extended 165 mm working distance. Mounted on a heavy-duty articulated spring-counterbalanced arm (900 mm reach) with an integrated forehead rest, it creates clearance for handpieces, files, and ball vises while relieving neck and lumbar strain during extended bench sessions.

Why Choose the Spring Arm Jewelry Microscope System

• 7X–45X Continuous Optical Zoom: Combines a 0.7X–4.5X zoom body with 10X wide-field eyepieces (WF10X/20 mm) and a 0.5X objective lens, delivering sharp 3D stereoscopic depth across a 5.1 mm to 33 mm field of view.

• Extended 165 mm Bench Clearance: The included 0.5X Barlow auxiliary lens doubles focal clearance to 165 mm, providing ample room below the optics for pneumatic handpieces, ball vises, and chasing hammers.

• Ergonomic Forehead Rest Support: Equipped with an integrated, adjustable padded headrest frame that stabilizes the operator's posture, reduces head tremors under high magnification, and eliminates neck and back fatigue.

• Multi-Directional Counterbalanced Spring Arm: Robust articulated spring arm extends up to 900 mm, allowing smooth multi-directional gliding and instant positioning over your jeweler's bench without occupying surface workspace.

• Anti-Fungus / Mildew-Treated Optics: Optical elements undergo specialized anti-mildew coatings to protect internal lenses and ensure lasting transmission clarity in humid workshop environments.
