<div class="aplus"> <p>The AmScope SM-3TYY-54S professional stereo zoom microscope has interchangeable pairs of 10x and 20x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, a 2.0x Barlow lens, and a single-arm boom stand. The microscope has an overall magnification range of 7x-180x. The trinocular viewing head has an interpupillary range of 55 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The WH10x20mm and WH20x10mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope comes with a 2.0x Barlow lens that can be added to the objective to increase the magnification range. A Barlow lens with a magnification greater than 1.0 increases the magnification and reduces the working distance. High-eyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected. </p> <p>The removable 54-bulb LED ring light provides bright, cool light for working with temperature-sensitive or live specimens. The ring light provides shadow-free illumination, and a rheostat controls the amount of light emanating from the lamp. Power and adjustment controls are located on the light head. The light uses a 110V-240V variable power supply. The microscope has a 17 pillar that has an 8 vertical working distance. The 16 single-arm boom has a 24 overall length. Bilateral focus eases use for left- and right-handed users. The microscope head can be rotated on the X- and Y-axes. The solid cast-steel base is 1-3/4 x 9 x 9 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back).</p> <table border="1" width="800" cellpadding="2" cellspacing="0"> <tbody> <tr bgcolor="#DFE1E0"> <th colspan="2" align="left"><b>Specifications</b></th> </tr> <tr> <td>Head</td> <td>Trinocular</td> </tr> <tr> <td>Magnification range</td> <td>7x-180x</td> </tr> <tr> <td>Zoom objective power<br /></td> <td>0.7x-4.5x</td> </tr> <tr> <td>Eyepieces (DIN, 30mm)</td> <td>WH10x20mm and WH20x10mm high-eyepoint</td> </tr> <tr> <td>Trinocular port</td> <td>C-Mount or 23mm</td> </tr> <tr> <td>Field of view</td> <td>1-1/4 </td> </tr> <tr> <td>Optical working distance</td> <td>Up to 4 </td> </tr> <tr> <td>Microscope stand</td> <td>Single-arm boom stand</td> </tr> <tr> <td>Head movement</td> <td>X- and Y-axes</td> </tr> <tr> <td>Illumination type</td> <td>Episcopic (reflected)</td> </tr> <tr> <td>Light source</td> <td>54-bulb LED ring light</td> </tr> <tr> <td>Power</td> <td>110V-240V</td> </tr> </tbody> </table> <br /> <p>Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mir</p> </div>
<p>This is a cordless LED binocular stereo microscope with top and bottom lights. It is designed for both indoor and outdoor applications, powered by either batteries or wall-power. It is portable and can be taken out to field sites. This microscope offers sharp clear stereo images, four magnification levels (20X-30X-40X-60X), and the freedom from cords. It comes with a rechargeable illumination system, three rechargeable AA batteries, and an AC adapter/charger. This durable and reliable microscope is a perfect instrument for viewing insects, plants, rocks, stamps, coins, jewel and etc. It is an ideal microscope for hobbyists and students. This microscope is brand new in factory-sealed box. </p> <p><b><u>Features :</u></b></p> <li>A great cordless stereo microscope with top and bottom LED lights</li> <li>Powered by either batteries or wall-power</li> <li>Convenient for being taken out for on-site applications</li> <li>Built-in rechargeable incident and transmitted LED illumination system</li> <li>10-LED top light</li> <li>7-LED bottom light</li> <li>Four magnification settings: 20X-30X-40X-60X</li> <li>45 degree inclined binocular head with locked-in eyepieces</li> <li>Adjustable interpupillary distance</li> <li>Sharp stereo erect images with wide field of view</li> <li>High quality original true color</li> <li>Ocular-tube with adjustable diopter</li> <li>Accurate alignment, ensuring fatigue-free viewing for hours </li> <li>Rugged metal frame and stand</li> <li>Full optical glass elements</li> <li>Precise ground glass lenses</li> <li>All metal mechanical components</li> <li>GS CE approval electric apparatus</li> <li>White/black plate and rubber eyeguards included</li> <li>Manufactured under ISO 9001 quality control system</li> <li>Excellent five (5) year warranty</li> <li>Unbeatable low price guaranteed or the difference back!</li> <li>Satisfaction guaranteed or your money back!</li> <p></p> <p><b><u>Specifications :</u></b></p> <li>Head: 45 degree inclined binocular</li> <li>Eyepiece: WF10X and WF15X</li> <li>Objectives: 2X and 4X</li> <li>Diopter Adjustment: +/-5dp</li> <li>Interpupillary Distance: 2-3/16" - 2-15/16"(55-75mm)</li> <li>Working Distance: 2-1/8" (53mm)</li> <li>Frosted Glass Objective Plate: 3-3/4" (95mm) in diameter</li> <li>White/Black Plastic Objective Plate: 3-3/4" (95mm) in diameter</li> <li>Illumination: 10-LED top light and 7-LED bottom light</li> <li>Accessories: a pair of eye-caps, a pair of clips and a dust cover </li> <p></p> <p><b><u>Packing List :</u></b></p> <li>One Forward Binocular Microscope with 2X & 4X Objectives, Pillar Stand and Top & Bottom LED Lights</li> <li>One Pair of Widefield 10X Eyepieces</li> <li>One Pair of Widefield 15X Eyepieces</li> <li>Three Rechargeable Batteries</li> <li>One Wall-Power AC Adapter/Charger</li> <li>One Frosted Glass Plate</li> <li>One Plastic Plate</li> <li>One Dust Cover</li> <li>One Pair of Eye-guards</li> <li>One Pair of Clips</li> <li>One Wrench for Tension Adjustment </li> <li>User's Manual</li> <li>Shipping Weight: 8 lbs</li> <p></p>
