AmScope SM-4NTPX Simul-Focal Stereo Microscope – 3.5X-45X Lockable Zoom, Dual-Arm Boom Stand

Meet the AmScope SM-4NTPX Simul-Focal Stereo Microscope, built for biological work, engineering, and precision inspection. This model blends a broad magnification range with a lockable zoom feature, so you can establish a steady view and maintain it as you examine samples or parts. The instrument’s design emphasizes reliable performance, flexible positioning, and camera-ready imaging for real-time documentation or analysis.

Flexible magnification and optical clarity

The SM-4NTPX delivers 3.5X-45X magnification through 0.7X-4.5X zoom objectives, paired with 10X wide-field eyepieces that provide an upright, depth-rich view. A 0.5X Barlow lens halves the magnification range to 3.5X-22.5X and increases working distance, enabling comfortable inspection of tall samples or larger components. The optics design yields a generous working distance and a useful field of view across the zoom range, helping you focus on details without compromising context.

• Zoom range: 0.7X-4.5X with a 0.5X Barlow for extended reach
• 10X wide-field eyepieces with high-eye-point comfort
• Native field of view: 4.4 mm–28.6 mm for varied samples

Camera-ready performance with simul-focal trinocular port

The simul-focal trinocular port shares the left objective with the left eyepiece, allowing a camera to stream live images while you retain full stereoscopic viewing with both eyes. This setup is compatible with CX-series ports and can be adapted to match specific cameras, supporting documentation, teaching, or remote collaboration.

• Simul-focal trinocular port enables live camera streaming
• CX-series compatibility allows easy port upgrades
• Ocular adjustment is handled with focusable eyepieces for consistent viewing

Sturdy stand and ergonomic design for real-world use

Mounted on a double-arm boom stand with ball-bearing movement, the SM-4NTPX offers stable, flexible positioning. The drop-down column and pivoting arms let you swing the head into position and move it away when needed. A heavy cast-steel base adds stability, even when attachments and accessories are in use. The design supports a wide range of workshop tasks, from meticulous assembly inspection to hands-on repair or engraving work.

• Double-arm boom stand with smooth, precise movement
• Heavy steel base for reliable stability
• Visual comfort: focusable eyepieces and adjustable interpupillary distance

What you get and where it shines

Ideal for laboratories, repair shops, and engravers, this microscope helps you observe depth, texture, and structure with confidence. Use it for quality checks, component inspection, or craftwork where a clear, controllable stereo image matters. While results depend on task and technique, the combination of a wide magnification range, a camera-friendly port, and a versatile stand makes the SM-4NTPX a capable teammate for busy workcells and studios.
