NSZ‑7 Series Stereo Microscope

Equipped with the innovative NIS apochromatic optical system, the NSZ‑7 achieves major improvements in resolution, depth of field, contrast and color reproduction, revealing fine details of tiny and complex specimens and redefining Greenough‑type stereo‑microscope performance. Its extra‑long 125 mm working‑distance offers ample safe space for instrument manipulation, boosting efficiency for live‑sample operations and industrial inspection. Boasting a class‑leading zoom range, it enables seamless observation from macro‑ to micro‑scale with responsive, user‑friendly controls.

Overview

Ultra-High Image Quality, Fine Detail

Breakthrough NIS apochromatic system fuses high contrast, high resolution and high color fidelity. From micro-structure observation to complex sample analysis, delivers superior imaging for efficient, accurate data acquisition.

Large Working Distance, Comfortable Operation

125 mm WD provides safe sample clearance and spacious under-scope working environment. Relaxed seated posture; minimal fatigue even during long sessions.

Macro-to-Micro Seamless Connection

NSZ709
1:9.1 zoom ratio; 6×–55× at 10× eyepiece. Fast switching between large-area and high-mag, high-res imaging.

NSZ707
1:7.5 zoom ratio (class-leading); 6.7×–50× at 10× eyepiece. High cost-performance for balanced performance and budget.

Supports Multiple Observation Modes for Wide‑range Applications

Transmitted / Reflected Brightfield

Balances high resolution and large depth of field. Plant tissue cell morphology, insect surface texture, PCB solder quality, precision-part assembly gaps — all rendered with authentic imagery, accurate color and sharp edges.

Darkfield

Professional darkfield illumination module with precise angle and intensity control. Detects fine scratches, cracks and transparent-sample defects in industrial QC.

Polarization

High-precision polarization module with accurate angle control. Mineral crystal identification, polymer internal-stress detection, biological tissue birefringence (starch grains, bone) — clear, detailed, color-rich images.

High-Contrast Imaging

Enhances brightness differences and boundary features. Layered 3D visual effect even for low-contrast or transparent samples.
