XSZ100 Jewelery Gemology Microscope

The XSZ100 is an inclined binocular stereo microscope with a 1X-4X zoom objective and a 90mm working distance, designed for detailed inspection of gemstones, jewellery components, and small precision parts.

Product Overview

The XSZ100 is an inclined binocular stereo microscope with a 1X-4X zoom objective and a 90mm working distance, designed for detailed inspection of gemstones, jewellery components, and small precision parts. It features a 360° rotatable head and dual illumination systems - incident halogen and transmitted LED - allowing clear viewing under different lighting conditions. The standard configuration includes a SWF10X eyepiece and a 12V/10W halogen lamp, with optional auxiliary objectives and accessories for expanded use.

  • Optical systemGreenough
  • HeadInclined Binocular
  • Head rotation360°
  • Zoom range1X-4X
  • Working distance90.5mm
  • Field of view22-5.5mm

Key Benefits

  • 90mm working distance allows room for tweezers, polishing tools, and small components under the optics
  • 360° rotatable head enables easy viewing from multiple angles without repositioning the specimen
  • Dual illumination: incident halogen for surface detail and transmitted LED for transparent or translucent materials
  • 1X-4X zoom range with 22mm to 5.5mm field of view covers both locating and inspecting fine features
  • Optional auxiliary objectives extend the zoom range to 0.7X-3.6X with a working distance of 86mm
  • Standard SWF10X eyepiece provides a wide field of view for efficient inspection
  • Inclined binocular head reduces neck strain during prolonged use

Application Scenarios

  • Gemstone grading and inclusion inspection under incident light
  • Jewellery repair and setting verification with a clear view of small prongs and bezels
  • Inspection of watch components and micro-mechanical parts in a precision workshop
  • Quality control of small metal or plastic parts in jewellery manufacturing
  • Teaching gemology or jewellery making techniques using a shared view with a monitor or camera

Who It Is For

  • Jewellery makers and repair specialists handling fine gemstones and small parts
  • Gemologists and gemstone graders in laboratories or retail settings
  • Precision assembly workshops in watchmaking and micro-mechanics
  • Educational institutions teaching gemology, jewellery design, or micro-inspection
  • Quality control teams in jewellery manufacturing for incoming and in-process inspection

Problems It Solves

  • A fixed head or non-rotatable design forces the operator to reposition the specimen for each angle
  • Short working distance limits the use of tweezers or tools during inspection
  • Lack of dual illumination makes it hard to inspect both opaque and transparent materials
  • No zoom range forces the operator to switch objectives for different inspection tasks
  • Standard eyepieces with narrow fields of view increase inspection time and eye strain

Technical Features

  • Greenough optical system provides true stereo depth perception across the zoom range
  • Inclined binocular head with 360° rotation for flexible viewing angles
  • 1X-4X zoom objective with a working distance of 90.5mm and field of view from 22mm to 5.5mm
  • Optional 0.75X, 0.5X, 1.5X, and 2X auxiliary objectives extend the zoom to 0.7X-3.6X with 86mm working distance
  • Incident illumination with 12V/10W halogen lamp for surface detail
  • Transmitted illumination with LED for transparent or translucent materials
  • Standard SWF10X eyepiece with Ø22mm barrel diameter
  • Optional WF10X, WF15X, and WF20X eyepieces available for different magnification needs
  • Included jewel tweezers and darkfield attachment with diaphragm for enhanced contrast

Customization Options

  • Choose between binocular and trinocular head configurations
  • Add optional auxiliary objectives (0.75X, 0.5X, 1.5X, 2X) to extend zoom and adjust working distance
  • Upgrade eyepieces to WF10X, WF15X, or WF20X for higher magnification or narrower fields
  • Select between incident halogen and transmitted LED illumination based on specimen type
  • Add a darkfield attachment or other accessories for enhanced contrast in specific applications

Comparison With Other Options

XSZ100 without auxiliary objectivesThe standard 1X-4X zoom offers a fixed range; adding auxiliary objectives extends the zoom to 0.7X-3.6X with a longer working distance for larger specimens
Flat-top stereo microscopeThe inclined head reduces neck strain during long inspections; the 360° rotation allows easier access to different angles without moving the specimen
Digital microscope with LCD screen onlyThe XSZ100 maintains binocular stereo vision for hand-guided work, while the camera can be added separately for documentation

Use Guide

  • Adjust the interpupillary distance to match your eye spacing before focusing to ensure a merged image
  • Use the incident halogen lamp for opaque materials like gemstones and metal parts
  • Switch to transmitted LED illumination for transparent or translucent materials such as crystals or glass
  • Attach the darkfield attachment with diaphragm to enhance surface texture visibility on polished or reflective surfaces
  • Use the 0.75X auxiliary objective to increase working distance and reduce magnification for larger specimens
