Key Features:7X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses and a 2X Barlow lens.A highly-versatile stereo microscope on a robust single-arm boom-stand which allows the microscope to be positioned at virtually any angle.Dual diopters can be adjusted to maintain consistent focus throughout the magnification range, greatly improving productivity.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 3MP USB 3.0 camera. Professional microscopy software for Windows, Mac, and Linux provide tools for image processing, measuring, and more.A 150W halogen illuminator with two heavy-duty fiber-optic attachments: a 35"" ring-light and 22"" dual-goosenecks. Active cooling and auto-shutoff avoids overheating in strenuous environments.The SM-3TP 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. With its wide zoom range and single-arm boom-stand, this model will become an indispensable instrument in any workshop or lab. This trinocular model has an additional port for mounting a camera, which is simul-focal so it can be used simultaneously with both eyepieces. OpticsThe 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. 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 Dual ocular diopters can be adjusted to maintain consistent focus, greatly improving productivity. 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. Single-arm Boom-Stand The multi-pivoting stand provides a stable, flexible support system, ideal for hands-on work. The single-arm design provides heavy-duty support in a simple form. The head can be turned 360°, the focus-block can swing in either direction, and the lateral arm can rotate and swing to position the head at virtually any angle. The heavy, steel base ensures the stability of the microscope, even when laden with attachments. Digital ImagingMonitor and capture photos and videos with the included 3.0MP USB3.0 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. The USB 3.0 connection provides greater bandwidth for faster frame-rates. A 0.37X reduction lens is included for use with 23mm-30.5mm ports 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. Additional ItemsThis package includes a powerful 150W illuminator with a ring-light and dual fiber-optic goosenecks. The incandescent light-source projects ultra-bright, full-spectrum light which is channeled through either of the included fiber-optic attachments. The dual 22"" gooseneck light-guides allow you to use two sources of direct lighting from virtually any angle. The 35"" ring-light attachment provides the smoothest ring of encompassing overhead illumination when attached to the microscope's objective housing. The flexible, heavy-duty metal-sheathed guides will hold up to heavy use in your workshop, factory, or lab without worry of crimping or breaking. The light-source is equipped with an active cooling system and an auto-shutoff circuit to avoid overheating in strenuous environments.
