AmScope - 7X-45X Simul-Focal Stereo Zoom Microscope on Boom Stand with 144 LED Ring Light - SM-4NTP-144

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. Optics 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. 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. 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.
