Nikon SMZ-445 StereoZoom Microscope 83601 Set with 10X Eyepieces and C-LED Focusing Stand, includes the Nikon SMZ-445 (MMA23008) Stereo Microscope that delivers the outstanding optical performance you expect from Nikon 's cutting-edge stereoscopic zoom microscopes. Porro prisms enable a lightweight, compact zoom microscope like the included Nikon SMZ-445 Stereo (MMA23008) with 0.8x ~ 3.5x zoom magnification (Zoom Ratio 4.4:1). High quality images with superior flatness are achieved by following the optical design and quality criteria of all Nikon 's high performance stereoscopic microscopes . The multicoated lenses provide clear, bright and high contrast images. The long working distance of 100mm allows safe focusing even with specimens having markedly uneven surfaces. This is useful when using tweezers, dissection tools or a pipette during specimen manipulation. The inside of the zooming body is treated with a mold-resistant finish. This maintains the integrity of the microscope optics even in hot, humid environments. The newly developed C LED microscope stand features built-in diascopic and episcopic illumination. The light intensity of each illumination type can be adjusted individually, and both can be used simultaneously. The LED light source uses very bright LED bulbs. Since they have a very long life, they avoid the cost and trouble of frequent replacement. And while the MMD23500 Nikon C-LED Stand is compact and thin, it is designed to be robust for all uses. In addition to the microscope LED stand with built-in diascopic illumination, it also comes with dedicated 10x eyepieces with diopter adjustments for parfocality. Combining the Nikon SMZ-445 (MMA23008) with 10x eyepieces along with rubber eyecups makes for a perfect stereoscopic biological microscope. We are an Authorized US Distributor for Nikon Microscopes.
