The 440-440P Zoom Trinocular Stereo Microscope with plain base from National Optical is a professional-quality stereo microscope for industrial and educational settings. The head design provides full access to the eyepieces, while allowing you to directly mount video cameras and DSLRs to stream the view locally to monitors or projectors, capture and document specimens for later use and study, or use with internet applications such as online class work, webinars, and podcasts.The 0.75-4.5x eyepieces combine with the 10x objective for a magnification range of 7.5-45x, and the overall height adjusts 13.4-17" to accommodate larger objects. The large zoom ratio of 6:1 and a standard working distance of 110mm provide the flexibility to support a large number of potential applications while the addition of an auxiliary lens or substitute eyepieces extend the magnification up to a maximum of 180x.Optical System and Focusing Paired widefield 10x eyepieces are 45 inclined, with dual diopter adjustments, interpupillary adjustment from 55-75mmAccepts 23mm eyepiece reticleViewing head rotates 360 Continuous magnification 7.5-45xLarge dual focusing knobs with slip clutch to prevent damage to mechanismTension adjustment eliminates focus 'drift'Frame and Stage Professional, all-metal frame, gray enamel finishPort for mounting microscopy camera or DSLR (DSLR requires optional C-mount)Heavy-duty post mount with locking support collar, permits up or down adjustment of viewing head to accommodate different-sized objects on stageHeight adjusts 13.4-17" for larger objects
