Nikon SMZ-745 StereoZoom Microscope 83603 Set with 10X Wide Field Eyepieces and C-LED Epi/Dia Stand was developed especially to meet the needs of customers who demand more advanced features and higher performance from a stereo microscope. For these reasons, Nikon believes the SMZ745 microscope will become the new standard for stereoscopic zoom microscopes in the 21st century. The MMK30102 widefield eyepiece was designed especially for the SMZ745 stereo biological microscope and comes equipped with built-in diopter correction. This brings the image and the reticle into focus at the same time, making it easier to view images, while reducing eye strain. The Episcopic/Diascopic microscope stand features a trim design that makes handling samples much easier. The diameter of the stage glass in the diascopic stand has been widened to make it possible to view samples even in large Petri dishes. By using twin zooming objective optics developed exclusively by Nikon, the SMZ-745 (MMA36400) research microscope incorporates a convenient 6.3:1 zoom ratio, enabling observations at just the right magnification to match the sample. The zooming knob also features click stops which allow changes in magnification in 1X intervals from 1X to 4X without removing your eye from the eyepiece. And since it is easy to maintain the same magnification, efficiency is ensured, whether you are using the microscope by yourself or sharing it in a laboratory situation. Even though the Nikon SMZ-745 offers extremely high magnifications, they still provide the longest working distances of any microscopes in their class. This allows you to process and manipulate samples with ease, even while performing delicate or complex tasks. We are an Authorized US Distributor for Nikon Microscopes.
