Designed to accommodate large and small specimens, the Swift Optical M29TZ-SM99CL Stereo Zoom Trinocular Microscope makes it easy and comfortable for groups of people to share the view through the eyepieces. The head design provides full access to the eyepieces, while you stream the view locally to the included tablet and/or to monitors and projectors, capture and document specimens for later use and study, or use with internet applications such as online class work, webinars, and podcasts.

The binocular eyepiece configuration lets you view with both eyes open, which is not only more comfortable, but preserves true 3D stereoscopic vision with a rich depth of view. The two eyepieces are set at a comfortable 45° angle, and the head rotates in a full 360° circle so people standing or sitting at a table or desk can all enjoy the view without having to have everyone move to the eyepieces. Optically the microscope is outfitted with two 10x power eyepieces that, when combined with the objectives, provide magnifications from 10x to 40x with a stepless zoom mechanism that enables precise power selection anywhere between the minimum and maximum. The objectives are all parfocal and parcentered, so that little or no focus adjustment will be required when changing magnifications, and the center of the view will remain consistent when switching objectives. A left-eye diopter adjustment allows users to compensate for individual eye strength, and the eyepiece's interpupillary adjustment range makes it easy for all users to place their distance exactly where they need it.

The viewing head can be raised and lowered relative to the base for viewing flat or chunky specimens. The stage is integrated into the base to make viewing larger specimens like rocks, gems, textiles, and circuit boards easier. Upper and lower LED illuminators light the stage, and independent power control allows you to have just the upper LED on, just the lower, or both; a rheostat dimmer controls the brightness to provide the perfect amount of light. Two stage plates are included: a frosted glass that passes light without the harsh glare, and a reversible white/black contrast plate that provides a stark difference between your specimen and background to enhance the view.
