The ZM-4T matches high-resolution optics with a brawny boom-stand for demanding biological and industrial applications. The ZM series shows improvements in resolution, contrast, and distortion compared to our staple SM series. This model is especially popular in the QC, repair and engraving industries thanks to its ease-of-use and reliability. This trinocular model has an additional port for mounting a camera, so you can record video or photos without replacing an eyepiece. With its wide zoom range and double-arm boom-stand, this model will become an indispensable instrument in any workshop or lab. OpticsThe advanced optical system in the ZM series microscope produces higher resolutions throughout its zoom range, with stunning contrast and color accuracy. The 0.67X-4.5X objective lenses offer excellent focus-depth and a large working-distance, with symmetrical zoom knobs to easily move through magnifications. 10X and 25X eyepieces are included, as well as 0.3X and 2X Barlow lenses to provide an expanded magnification range from 2X-225X, with high-eyepoint optics to accommodate glasses or goggles. Ocular Adjustment Dual ocular diopters can be adjusted to maintain consistent focus, greatly improving productivity. Sliding interpupillary adjusters ensure that each user can properly align the eyepieces for comfortable viewing. 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. 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-bearings 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. Monitor 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. This package includes a powerful 150W illuminator with a fiber-optic ring-light. The incandescent light-source projects ultra-bright, full-spectrum light which is channeled through the 35” fiber-optic light-guide which provides the smoothest ring of encompassing illumination. The flexible, heavy-duty metal-sheathed guide 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.
