AmScope Trinocular Stereo Microscope SH-2 Jewelry Gem

Description

AmScope SH-2 Series Jewelry Gem Binocular Stereo Microscope 10X-40X Magnification on Pillar Stand with Three Lights

The AmScope SH-2 Jewelry Gem Trinocular Stereo Microscope 10X-40X is a professional trinocular stereo microscope designed specifically for gemstone inspection, jewelry evaluation, diamond grading, and precision surface examination. Combining a continuous 10X–40X zoom range with bright field, darkfield, and side illumination, this microscope provides the lighting flexibility required for examining both the surface characteristics and internal structures of gemstones.

Built around a robust all-metal pillar stand and precision optical system, the SH-2 Series delivers clear stereoscopic viewing with natural depth perception, making it suitable for detailed gemological work, quality control, and professional jewelry handling.

Designed for Gemology and Precision Inspection

Unlike standard laboratory microscopes, this stereo microscope is optimized for observing solid objects in three dimensions. The stereo optical design produces erect, true-color images with excellent contrast and depth, allowing users to inspect gemstone inclusions, facet edges, polishing quality, clarity features, and mounting details comfortably over extended sessions.

The integrated darkfield illumination system is particularly valuable for diamond and gemstone analysis. By directing light through the specimen from below while minimizing direct reflected light, inclusions and internal imperfections become significantly easier to detect.

The included fluorescent gooseneck side lighting box adds additional surface illumination from adjustable angles, helping reveal scratches, surface fractures, polishing marks, and fine jewelry craftsmanship details.

Continuous 10X–40X Zoom Magnification

The microscope features a 1.0X–4.0X zoom objective paired with WF10X widefield eyepieces, providing smooth continuous magnification from 10X to 40X without changing lenses.

Advantages of the Zoom System

• Quickly transition from low-magnification overview inspection to detailed close-up examination
• Ideal for grading gemstones of different sizes
• Maintains image sharpness and stereoscopic depth throughout the zoom range
• Large 4:1 zoom ratio improves workflow efficiency during professional inspection work

The generous 3-3/8" working distance provides sufficient space for handling jewelry tools, tweezers, gemstones, and mounted pieces beneath the objective.

Trinocular Head for Imaging and Documentation

The trinocular viewing head includes a dedicated photo port for attaching a microscope camera or video system. This enables:

• Gemstone photography
• Jewelry documentation
• Quality control imaging
• Educational demonstrations
• Digital archiving
• Live video inspection

The 45° inclined ergonomic design reduces neck strain during prolonged use, while the 360° rotatable head allows convenient positioning in shared workspaces or training environments.

Triple Illumination System for Gemstone Analysis

One of the key strengths of the SH-2 is its versatile three-light configuration.

Top Incident Halogen Illumination

Used for:

• Surface inspection
• Facet analysis
• Metalwork examination
• Engraving inspection
• Jewelry craftsmanship evaluation

Bottom Darkfield Transmitted Illumination

Designed for:

• Diamond clarity grading
• Inclusion detection
• Internal fracture analysis
• Gemstone transparency inspection

Gooseneck Fluorescent Side Lighting Box

Provides:

• Adjustable directional lighting
• Enhanced contrast on reflective surfaces
• Improved visibility of fine surface details
• Better observation of polish quality and edge definition

Together, these lighting options allow users to adapt illumination techniques to different gemstone types and inspection tasks.

Optical and Mechanical Quality

The microscope uses fully coated optical glass elements with precision-ground lenses to produce high-resolution images with excellent flatness and color accuracy. The all-metal mechanical construction improves long-term durability and maintains optical alignment during regular professional use.

Additional ergonomic features include:

• Adjustable inter pupillary distance (55–75mm)
• Diopter adjustment of ±5dp
• Rubber eye guards for viewing comfort
• Smooth zoom controls
• Stable pillar stand construction
