Nexius Zoom NZ.1903-P Trinocular Stereo Microscope with 0.67-4.5x Zoom and Dual 3W LED Illumination

The Nexius Zoom NZ.1903-P is a high-precision *trinocular stereo microscope* designed for detailed 3D observation in biotechnology, biomedical engineering, and molecular diagnostics. Its optical system features a *zoom objective* with a magnification range from 0.67x to 4.5x, providing a total magnification between 6.7x and 45x when combined with the supplied HWF10x/22 mm wide-field eyepieces. This wide magnification range supports a variety of life science workflows, including synthetic biology research and bioprocessing quality control.

Key technical specifications include:

• Optics: Zoom ratio 1:6.7; field of view from 33 mm to 4.9 mm; working distance 110 mm to accommodate diverse sample sizes critical for live-cell imaging and biomanufacturing inspection.
• Eyepieces: Pair of HWF10x/22 mm wide-field eyepieces with ±5 diopter adjustment for precise focusing tailored to user vision differences.
• Trinocular head: Inclined at 45°, featuring interpupillary distance adjustable from 54 to 75 mm, and a 50:50 light beam splitter port ideal for photo/video documentation during molecular cloning workflows.
• Objectives: Optional auxiliary lenses (0.5x, 0.75x, 1.5x, 2.0x) enable extended versatility for high-precision stereoscopic observation in cell imaging and biochemical analysis fields. Anti-fungal and anti-reflective coatings on all optical components ensure optimal light transmission and durability.
• Illumination: Dual independent 3 W LEDs provide both transmitted and incident illumination with intensity control, essential for detailed fluorescence analysis and multi-contrast sample examination. The internal power supply supports 100-240 VAC for global laboratory deployment.
• Mechanical design: Sturdy large-format flat base with height-adjustable column and a coaxial coarse focusing system employing precision ball bearing rack-and-pinion mechanism for smooth and stable sample positioning. The setup includes two sample clips for secure specimen handling during biotechnological and clinical applications.
• Package: Delivered with power cable, protective dust cover, spare fuse, and user manual in a polystyrene case, ensuring safe transport and longevity.

This microscope's wide zoom range, trinocular camera port, and dual LED illumination system make it an essential tool for molecular biology researchers, biomedical engineers, and professionals engaged in synthetic biology and biomanufacturing quality assurance. It supports complex biological sample assessments, making it highly suitable for gene editing validation workflows and clinical diagnostics laboratories requiring detailed stereoscopic visualization and digital imaging capabilities.
