Key Features:7X-135X extended zoom magnification using high-quality Greenough stereoscopic objective lenses with 10X and 15X eyepieces, 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 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 18MP USB 3.0 camera. Professional microscopy software for Windows, Mac, and Linux provide tools for image processing, measuring, and more.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 and 15X eyepieces are included, as well as a 2X Barlow lens to provide an expanded magnification range from 7X-135X, with high-eyepoint optics to accommodate glasses or goggles. 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 18.0MP 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 0.5X 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.
