AmScope SM-4TPZ Trinocular Stereo Zoom Microscope with Boom Stand – 0.7x-4.5x, 3.5x-90x Magnification, Ambient Lighting, 0.5x & 2.0x Lenses

Overview

Meet the AmScope SM-4TPZ, a professional trinocular stereo zoom microscope engineered for demanding bench work, classrooms, or workshop setups. Mounted on a double-arm boom stand, it offers a generous working distance that helps you maneuver larger items—ranging from circuit boards to dental appliances—without crowding the field of view. The system includes simultaneous focus control, so you can refine sharpness while sharing the view with collaborators.

Optical versatility and magnification

The instrument benefits from a 0.7x-4.5x zoom objective paired with 10x super-widefield eyepieces, delivering a broad magnification spectrum (3.5x-90x) that supports both broad overviews and fine detail work. The 0.5x and 2.0x Barlow lenses further extend the range, providing longer working distance or increased magnification as needed.

Illumination and observation

Ambient lighting illuminates the specimen directly, removing the need for external lamps or batteries. This keeps the setup simple and reduces clutter, while delivering consistent visibility across a variety of specimens and surfaces.

Stability and positioning

The double-arm boom stand measures 20 inches per arm and 17 inches high, enabling precise positioning of the microscope head along X, Y, and Z axes. This flexibility is especially useful when working with sizable or irregularly shaped items that require careful alignment.
