The, BRESSER ETD-101 7-45x Zoom Stereo Microscopehas a relatively low magnification range with true stereoscopic vision for making detailed observation of larger specimens like bugs and insects, plants and flowers, gems and jewelry, coins and textiles, and more. The 10x wide-field binocular eyepieces and single zoom objective produce between 7x and 45x powers with both upper and lower illumination for solid, transparent, or semi-transparent specimens. The stereo design produces true 3D images with a rich depth of field to more easily discern textures and contours that are usually flattened in traditional compound microscopes.

Its large base acts as the stage with two changeable object plates that allow you to better control the light tone and texture to match your subjects. When using the upper incidental light, you can choose either the black or white side of the object plate that best improves the contrast. Use the frosted object plate with the lower transmitted light source to soften and diffuse the light coming through. Each halogen bulb has its own dimmer and power switch to give you absolute control of the available light. The illuminators run on 230VAC European power.

• Stereo microscope produces a true 3D image with a rich depth of field—ideal for observation studies in medicine and health, farming and forestry, public security departments, and schools and scientific research institutes, as well as for inspection, assembling, and repair of tiny parts in electronics and precision machine industries
• Binocular eyepieces improve viewing comfort, especially when using for long periods
• Eyepieces are angled 45° to body to place the head in a comfortable viewing position
• Head rotates a full 360° to make sharing around a lab table easier
• Two 10x wide-field eyepieces produce between 7x and 45x when paired with the zoom objective
• 0.7-4.5x zoom objective produces relatively low magnifications for larger specimen examination and inspection
• Large 30.5mm eyepiece barrel diameter presents a large field of view
• ±5 diopter correction on both eyepieces ensures crisp and sharp focusing for almost any user—even if they normally wear eyeglasses
• Wide 53-75mm interpupillary adjustment range allows easy use by a wide variety of people
• Winged rubber eyecups block side peripheral light during observation to improve contrast

• Wide working distance: Move head/objective up and down on the stand for the proper clearance
• Single-speed focus knob
• Upper (incident) and lower (transmitted) 10W halogen illumination with dimmers
• Choose either upper only, lower only, or both to perfectly illuminate specimens
• Changeable objective plate provides the ability to change the character and tone of selected light
• Black/white object plate: Black on one side, white on the other improves contrast of specimen when using upper (incident) light
• Frosted finish object plate: When using lower (transmitted) light, it softens and diffuses the halogen light for more comfortable and consistent light coming into the specimen
• Integrated slide/specimen clips
• Runs on European 230 VAC power
