NexiusZoom EVO Gemmologie NZ.1703-GEMF — Stereomicroscope with 6.5–55x zoom and trinocular 45° head (Euromex)

The NexiusZoom EVO Gemmologie NZ.1703-GEMF is a purpose-built stereomicroscope for gemmology, offering wide magnification flexibility, a comfortable viewing angle and both reflected and transmitted illumination for crystal‑clear stone assessment.

• 6.5–55x zoom range for detailed inspection
• Trinocular 45° head for ergonomic viewing
• Combined incident and transmitted illumination

High‑resolution inspection for precise gem grading

The optical system delivers a 6.5–55x working magnification based on a zoom 0.65–5.5x objective and HWF 10x/23 mm eyepieces, giving a practical zoom ratio of 1:8.4 with click‑stops for repeatable settings. The optics are treated with an antifungal coating and an anti‑reflective coating, which reduce stray reflections and protect lenses in humid environments. This combination allows consistent surface and inclusion evaluation while reducing observer fatigue; the fixed optical parameters make documentation and comparison straightforward.

Ergonomic design that supports long inspection sessions

An ergonomically inclined trinocular 45° head and an adjustable interpupillary range of 54–75 mm reduce neck strain and permit comfortable binocular viewing for extended periods. The coarse focus has adjustable friction, enabling steady, vibration‑resistant focusing during fine inspection. A ±5 dioptre adjustment on both eyepieces accommodates individual eyesight differences without auxiliary lenses. The generous 110 mm working distance allows convenient handling of stones and tools beneath the optics, improving workflow and safety when setting or examining mounted gems.

Lighting and imaging for reliable contrast and documentation

Integrated illumination combines reflected light (incident) via a 7 W fluorescent lamp and transmitted light (through‑illumination) via a 30 W halogen source, giving both surface detail and internal contrast as required for gemmological analysis. A supplied darkfield transmitted unit with an iris diaphragm enhances edge definition and reveals inclusions. For image capture, the instrument offers a photo connection but requires a specified sensor size and an additional SLR adapter (AE.5040) for standard camera mounting; certain heads and sensors are available as options. Note that auxiliary front lenses must not be used in combination with the darkfield adapter (see accessory restriction NZ.9525) to avoid optical conflicts.

Complete delivery and configurable options for professional labs

The supply scope includes an object clamp, the darkfield transmitted unit with iris, mains lead, dust cover, spare fuse and operating instructions, which supports immediate use in a laboratory environment. Several exchange/configuration heads are available (NZ.5302, NZ.5303, NZ.5312, NZ.5313) to tailor the rig to specific imaging or inspection needs; photo interfaces (NZ.9850) will require the correct sensor specification. The instrument’s robust configuration makes it well‑suited to gemmology benches, university labs and professional inspection stations that require a combination of optical precision and practical handling.

FAQ

What magnification range does the stereomicroscope cover?
The NexiusZoom EVO Gemmologie NZ.1703-GEMF provides a 6.5–55x magnification range via its zoom 0.65–5.5x objective and HWF 10x eyepieces, allowing both overview and detailed inclusion inspection.

Is the instrument suitable for photographing gemstones?
Yes — the trinocular head supports imaging, but the NZ.1703-GEMF requires a photo connection with a designated sensor size and often an additional SLR adapter (AE.5040); camera bayonet compatibility should be checked before purchase.

Which illumination modes are available for inspection?
The NZ.1703-GEMF includes reflected illumination with a 7 W fluorescent lamp and transmitted illumination via a 30 W halogen lamp, plus a supplied darkfield transmitted unit with iris diaphragm for enhanced contrast.

Can the head angle and focus be adjusted for comfort?
The trinocular head is set at 45°, the stand tilts 0–45° backwards, interpupillary distance is adjustable from 54–75 mm, and the coarse focus features adjustable friction for steady focusing during prolonged use.

What is included in the delivery and which optional heads are available?
Delivery contains an object clamp, the darkfield transmitted unit with iris, mains lead, dust cover, spare fuse and manual. Exchange/configuration heads (NZ.5302, NZ.5303, NZ.5312, NZ.5313) and photo options (NZ.9850) are available as extras.
