AmScope SM-2 Series Trinocular Stereo Microscope 3.5X-45X w/ LED Dual Lights

3.5×-45X extended zoom magnification using high-quality Greenough stereoscopic objective lenses and a 0.5X Barlow lens. 100mm-165mm working distance Super widefield optical system offering crystal clear images Top and bottom LED lights with separate dimmers provide incident and transmitted illumination for viewing biological specimens and industrial materials alike Heavy-duty pillar stand with metal framework combines all of the functionality needed in a compact, stable form Trinocular port for adding photo or video capability This is a first-class trinocular stereo zoom microscope with LED cool illumination system. Designed to meet the demands of the modern microscopy applications that are temperature-sensitive, like dissecting live tissues or observing live creatures, this scope exceeds all expectations. It incorporates all the most excellent features of a high quality laboratory instrument. This microscope comes with SUPER widefield optics and versatile LED illumination system that provides both incident (top) cool lighting and transmitted (bottom) cool illumination. You can choose between incident illumination shining down onto the object or transmitted illumination through the frosted stage plate. The first is used for the observation of three-dimensional objects and the second for the inspection of the objects that allow light to get through them. Optics The stereo optics provide clear, sharp images with excellent focus-depth and a large working-distance. With 0.7×-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 0.5X Barlow lens is included, which can be mounted to the objective housing to halve the magnification range to 3.5×-22.5X. This also increases the working distance. The combined magnification ranges provide 3.5×-45X. 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. Dual-Illumination Stand The dual-illumination stand provides a turnkey solution for biological and industrial applications. The pillar-based support system offers flexibility with its ability to quickly adjust height and lateral position. The microscope can be easily set and rotated in the mounting collar, and locked in place once adjusted. Large, symmetrical focus knobs provide the precision control needed, with adjustable tension for light or heavy loads as well as comfort. Overhead and sub-stage LED lighting allows you to work with opaque and translucent objects. The top light is mounted behind the head to provide offset light, and can be tilted for varied effect. This is useful for topological examination, such as with circuit boards and biological cultures. Thin tissue specimens, gemstones, and other translucent materials will benefit from the sub-stage transmitted lighting. A frosted glass stage-plate is provided to diffuse the light for more even back-lighting.
