The inverted format of this microscope offers the ability to view a wide range of specimen types and shapes. The 5W LED episcopic illumination system provides reflected illumination for opaque specimens such as metals, minerals, and manufactured materials. The trinocular viewing head allows you to attach a camera for recording images or to view specimens on a screen. This microscope is ideal for metallurgy and geology labs. Using four plan-achromatic objective lenses from 5X to 50X, a broad range of magnifications can be covered. These highly corrected lenses produce sharp, flat images from 50X to 1250X when used with the included 10X and 25X eyepieces. A inverted metallurgical/metallographic microscope with Plan optics Wide band power supply system from 90V to 240V for international use Trinocular head for adding photo/video capability Fully coated optical system with high resolution Four Plan objectives included Variable-intensity LED illumination Large mechanical stage with stain resistant finish Coaxial coarse and fine focusing Focusing tension control mechanism Low position stage traveling controls Full optical glass elements Dual side focusing controls Adjustable interpupillary distance Adjustable diopters on both eye tubes Monitor and capture photos and videos with the included 1.3MP USB2.0 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. 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.
