NexiusZoom Gemmologie NZ.1903-GEMF — Gemmology stereomicroscope with 6.7–45x zoom and trinocular 45° head (Euromex)

The NexiusZoom Gemmologie NZ.1903-GEMF is a dedicated gemmology stereomicroscope offering a broad magnification range and photographic readiness for laboratory and trade use

• 6.7–45x magnification range
• Trinocular 45° head for imaging
• Incident 7 W + transmitted 30 W illumination
• 110 mm working distance for gem handling

Sharper detail for reliable gem assessment

The optical train delivers a 6.7–45x magnification range with a zoom 0.67–4.5x objective and a zoom ratio of 1:6.7, enabling close inspection of inclusions and surface features without frequent objective changes. The optics feature anti-fungal treatment and anti-reflection coatings to maintain contrast and reduce stray light; combined with HWF 10x/22 mm eyepieces, this provides a clear, stable image that supports repeatable assessments and consistent quality control.

Reliable illumination and camera-ready imaging

A dedicated illumination concept combines incident light (7 W fluorescent, non-dimmable) with transmitted light (30 W halogen) to reveal internal structure and surface detail with faithful colour reproduction. The trinocular 45° head permits simultaneous observation and imaging; photographic integration is supported but requires the specified adapters (see technical accessories). Note that certain accessories are incompatible or require a specific sensor size, so correct camera coupling is essential for reproducible documentation.

Comfort and control for extended examination sessions

Ergonomic adjustments reduce fatigue during prolonged use: interpupillary distance 54–75 mm, dioptre compensation ±5 each side and a coarse focus with adjustable friction for fine tactile control. The stand is a gemmology variant, tilting backwards 0–45°, which adapts to inspection angles while keeping the 110 mm working distance clear for tweezers and probes. At a weight of 8.4 kg and compact footprint of 510 x 260 x 310 mm (H x W x D), the unit remains stable on standard benches without occupying excessive space.

Prepared for immediate use and future upgrades

Delivered accessories include an object clamp, a darkfield transmitted unit with iris diaphragm, mains lead, dust cover, spare fuse and instruction manual, so the instrument is operational from delivery. Modular upgrade options exist for alternative heads and photographic interfaces (refer to accessory codes), while some configurations must not be combined with specific front lenses. The system is aimed at gemmology and fine-detail inspection tasks where optical fidelity and adaptability are primary requirements.

FAQ

What magnification range does the instrument cover?
The NexiusZoom Gemmologie NZ.1903-GEMF provides a magnification range of 6.7–45x, enabled by a zoom objective of 0.67–4.5x and HWF 10x eyepieces.

Is the head suitable for photography and which adapters are required?
The trinocular head supports imaging; camera connection requires dedicated adapters such as AE.5040 or AE.5020 and attention to camera bayonet and sensor size for correct coupling.

Can the lighting be adjusted during use?
The incident light is a 7 W fluorescent non-dimmable lamp and the transmitted illumination is a 30 W halogen unit; the combination offers balanced inspection lighting but the incident lamp is not dimmable.

What ergonomic adjustments are available for different operators?
Interpupillary distance is adjustable 54–75 mm, dioptre compensation is ±5 on both eyepieces and focus friction can be tuned for personalised handling.

Which accessories are included and which are optional?
Included: object clamp; darkfield transmitted unit with iris diaphragm; mains lead; dust cover; spare fuse; manual. Optional heads and photo accessories are listed under the accessory codes and must be checked for compatibility.
