Amscope 7X-90X Simul-Focal Stereo Zoom Microscope on Boom Stand with 144 LED Light and 1.3MP USB Camera




Key Features:

  • 7X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses and a 2X Barlow lens.
  • The microscope provides up to 4" (100mm) of working distance.
  • A highly-versatile stereo microscope on a heavy-duty, multi-pivot boom-stand which allows the microscope to easily swing into place when needed, and away when not.
  • The zoom lenses can be locked to maintain a consistent magnification.
  • The stereo optics provide upright images with clear depth-of-field and a wide view for hands-on applications.
  • The simul-focal trinocular photo-port provides a dedicated mount for a camera, and can be used simultaneously with both eyepieces.
  • This microscope is ideal for laboratories, repair shops, and engravers.
  • Monitor and capture photos and videos with the included 1.3MP USB 2.0 camera. Professional microscopy software for Windows, Mac, and Linux provide tools for image processing, measuring, and more.
  • The 144-LED ring-light produces an encompassing field of bright light with reduced shadows for use with any application, and it uses a convenient control module to adjust brightness.


The SM-4NTP is a heavy-duty, highly-flexible microscope designed for biological and industrial applications. This model is especially popular in the QC, repair and engraving industries thanks to its ease-of-use and reliability. This model features a zoom-lock to maintain consistent magnification when needed, and uses focusable eyepieces rather than integrated dioptric adjusters. With its wide zoom range and double-arm boom-stand, this model will become an indispensable instrument in any workshop or lab. The trinocular photo-port is simul-focal, so it can be used simultaneously with both eyepieces.


The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7X-4.5X zoom objectives, moving through the magnification range is as easy as turning a knob. A zoom-lock allows the objectives to be set to a consistent magnification when needed. 10X wide-field eyepieces provide an ample magnification range from 7X to 45X, with high-eyepoint optics to accommodate glasses or goggles. A 2X Barlow lens is included, which can be mounted to the objective housing to double the magnification range to 14X-90X. This will also result in decreased working distance. The combined magnification ranges provide 7X-90X.

Ocular Adjustment

The ocular tubes are not equipped with dioptric adjusters, so focus is more consistent. Focusable eyepieces are included to compensate for vision irregularities, and are available in various optional magnifications. Rotating interpupillary adjusters simplify the process of aligning the eyepieces for each user.

Simul-focal Trinocular Port

The simul-focal optics in this microscope allow the trinocular port to be used simultaneously with both eyepieces. This means a camera can stream live images from the microscope while you continue to work with full stereoscopic vision. This is accomplished by sharing the left objective lens with the left ocular and the photo-port. This microscope uses our CX series trinocular port, so it can be easily replaced with optional C-mount ports to match specific cameras.

Double-arm Boom-Stand

The multi-pivoting, double-arm stand provides a stable, flexible support system, ideal for hands-on work. Use of a drop-down column allows the head to be positioned at virtually any angle. Ball-bearing provide smooth movement of the lateral arms, which can easily pivot the microscope out of the way when it is not needed. The heavy, steel base ensures the stability of the microscope, even when laden with attachments.

Digital Imaging

Monitor and capture photos and videos with the included 1.3MP USB2.0 camera. The C-mount camera is specially designed for use with microscopes, allowing you to watch live images, and to record photos or videos on your computer. This ability to view microscopic images on your computer reduces eye-strain, and allows groups of people to view images at the same time. A 0.37X reduction lens is included to capture more of the microscope's field-of-view. Our professional software for Windows provides a wide assortment of capture and photo-editing functions including color correction, time-lapse capture, image stitching, and a full complement of measuring tools. A lite version of our software is available for Mac and Linux with essential functionality for capturing photos and videos.

This package includes a 144-LED ring-light for bright and cool illumination. This lightweight illuminator mounts to the microscope’s objective housing, and projects a smooth, encompassing field of light over objects, eliminating most shadows. For added convenience, a separate power-controller is used to manage the brightness. Whether used as the sole light-source or in combination with additional illuminators, the ring-light produces a crucial light pattern for virtually any application. Energy-efficient and producing low heat, this ring-light can be used with biological specimens as well as industrial.
