The SW350T keeps all the features of our popular SW350B: the interchangeable wide-field 10X and 25X eyepieces are mounted into a swiveling Siedentopf head, allowing for quick adjustments to suit different interpupillary distances without loss of focus. The four achromatic DIN objectives -- 4X, 10X, 40X(Spring), and 100X (Spring, Oil) -- combine with the eyepieces for 6 powerful magnification levels between 40X and 2500X. An LED bulb provides steady, brilliant illumination fully controlled by the dimmer wheel and focused through an industry-standard NA 1.25 Abbe condenser and iris diaphragm. A large mechanical stage with a moveable slide holder allows you to see the entire area of a specimen without reclipping. The SW350T also introduces a third ocular tube on which an additional eyepiece or a microscope camera (not included) can be mounted, allowing users to stream and record video as well as capture pictures of specimen images.
