Key Features:3.5X-90X extended zoom magnification using high-quality Greenough stereoscopic objective lenses with 0.5X and 2X Barlow lenses.A highly-versatile stereo microscope on a robust single-arm boom-stand which allows the microscope to be positioned at virtually any angleDual 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.A trinocular photo-port provides a dedicated mount for adding a camera.This microscope is ideal for laboratories, repair shops, and engravers.Monitor and capture photos and videos with the included back-illuminated 20MP 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 dual 22"" fiber-optic gooseneck light-guides provides two sources of direct lighting from virtually any angle. Active cooling and auto-shutoff avoids overheating in strenuous environments.The SM-3T 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, so you can record video or photos without replacing an eyepiece. 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. 0.5X and 2X Barlow lenses are included, which can be alternated to either halve or double the magnification range, expanding the possible magnifications to 3.5X-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. Trinocular Port The switched trinocular photo-port provides a dedicated mount for a camera. When the photo-port is switched open, all light from the left objective is diverted to the port to provide maximum brightness for the camera to guarantee the best quality images. 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 high-resolution 20MP USB3.0 camera. The sensitive back-illuminated sensor is designed for improved low-light imaging, making it suitable for fluorescence and darkfield microscopy. 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 dual fiber-optic goosenecks. The incandescent light-source projects ultra-bright, full-spectrum light which is channeled through dual 22"" gooseneck fiber-optic light-guides. This allows you to use two sources of direct lighting from virtually any angle. 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.
