NexiusZoom EVO NZ.1702-GEML — Binocular stereo microscope with 0.65–5.5× objective zoom and 6.5–55× magnification

The NexiusZoom EVO NZ.1702-GEML is a binocular stereo microscope designed for professional gemological inspection, combining a wide zoom range with simultaneous bright- and darkfield capability for detailed stone evaluation

• Binocular stereo microscope, zoom 0.65–5.5×
• Magnification range 6.5–55× for gemology
• Gemology tilt stand, arm adjustable 0–45°
• Integrated 1 W LED top and 30 W halogen bottom

Clearer decisions through a wide, high‑precision zoom

The integrated objective zoom (0.65–5.5×) paired with 10× HWF eyepieces yields a magnification range of 6.5–55×, allowing systematic examination from overview to detail without changing optics. The zoom ratio 1:8.4 ensures smooth, proportional scaling for faster defect localisation and comparison. A working distance of 110 mm permits manipulation of gemstones and the use of tweezers or clamps while maintaining optical clarity. The object field spans from 35.4 mm to 4.2 mm, enabling both contextual inspection and fine-grain analysis in the same setup.

Reliable, controllable lighting for contrast and inclusion study

Integrated illumination combines a 1 W LED incident light and a 30 W halogen transmitted light, each with brightness control. The transmitted lamp operates at 6 V, while the internal power supply accepts 100–240 V AC, offering stable performance across regions. The optical train supports both brightfield and darkfield modes and allows simultaneous top and bottom illumination, which improves visibility of surface features, internal inclusions and interference effects. An iris diaphragm refines contrast and depth of field, so clarity is achieved without complex adjustments.

Ergonomic rigging and optical care for long sessions

The dedicated gemology tilt stand provides an adjustable arm from 0° to 45°, enabling comfortable, fatigue‑reducing working positions during extended inspections. The binocular head accepts a 76 mm mounting diameter and supports a pupillary distance of 54–75 mm, with diopter compensation from −5 to +5 dpt to accommodate individual operators. Optics are anti‑fungal treated and anti‑reflective coated, reducing maintenance cycles and preserving image contrast in humid or variable environments — a practical safeguard for benches that process many specimens each day.

Ready for the bench: accessories and practical essentials

Delivered items include 2 HWF eyepieces 10×/23 mm, an object clamp (positionable on the right or left), power cable, dust cover, spare fuse and user manual. The head is binocular, and the system permits direct switching between hellfeld and dunkelfeld observation for comprehensive gemological workflows. The combination of robust mechanics and accessible controls reduces setup time and contributes to reproducible, documented inspections within quality assurance processes.
