NexiusZoom Gemmologie NZ.1902-GEML stereomicroscope — 6.7–45x zoom with dual illumination (Euromex)

The NexiusZoom Gemmologie NZ.1902-GEML is a specialised stereomicroscope designed for gemmological examination, offering a wide magnification range and combined reflected and transmitted lighting for comprehensive stone assessment.

• 6.7–45x zoom for detailed image capture
• Dual illumination: dimmable LED and 30 W halogen
• 110 mm working distance for larger samples
• Gemmology stand tiltable 0–45° for angled inspection

Accurate enlargement for detailed gemstone evaluation

The instrument delivers a 6.7–45x magnification range through a zoom 0.67–4.5x objective combined with HWF 10x/22 mm eyepieces, enabling fine resolution of inclusions, facet junctions and surface features. The zoom ratio 1:6.7 offers smooth, continuous scaling that supports both rapid overview and high‑magnification scrutiny. This optical flexibility reduces the need for multiple objectives and accelerates workflow in busy laboratories and workshops, while the antifungal treatment and anti‑reflective coating preserve image quality and extend service intervals.

Versatile illumination for true colour and clarity assessment

Lighting significantly influences visual assessment; the system combines a dimmable 1 W LED for reflected (surface) inspection with a 30 W halogen transmitted source for internal structure and transparency checks. The supplied darkfield transmitted unit with iris enhances contrast for inclusions and fractures, making diagnostic features more visible without complex sample preparation. Adjustable light intensity supports calibrated visual grading and photographic documentation under repeatable conditions, improving consistency between inspections.

Ergonomic design for extended inspection sessions

An uninterrupted 110 mm working distance accommodates larger mounts and handling tools while keeping samples accessible. The binocular 45° head and tiltable gemmology stand (backwards 0–45°) combine to reduce wrist strain and permit comfortable angled viewing during prolonged tasks. Optical adjustments include diopter ±5 on each side and a pupillary distance of 54–75 mm, allowing precise personalisation for different operators. Coarse focusing with adjustable friction secures set positions and speeds up specimen alignment, which is particularly valuable in production or educational settings.

Complete equipment and configurable options for specialised workflows

The unit is supplied ready for professional use with an object clamp, darkfield transmitted unit with iris, mains lead, dust cover, spare fuse and instruction manual, ensuring immediate deployment. Several exchange/configuration heads (NZ.5302, NZ.5303, NZ.5312, NZ.5313) are available to adapt the head to different inspection protocols; note that the NZ.9525 accessory must not be used with supplementary objective lenses. The instrument’s build integrates practical features for maintenance and longevity, supported by documented accessory compatibility for future upgrades or reconfiguration.
