This is a 7-45X continuous-zoom trinocular stereo microscope head with a simultaneously-active photo port. This design removes the need to disable an ocular port to use the photo port, instead routing the image continously to your imaging system. It includes a pair of focusable 10X high-eyepoint, super wide-field eyepieces. View sharp, erect stereo images over a wide zoom range, with 45-degree inclined ocular tubes. Designed to fit 3" (76mm) collars, the head can be used with a huge range of support systems, including most of our column stands, and single- and double-arm boom stands.

Different from our SM745TP model, this head has moved the diopter-adjustment from the ocular ports to the individual eyepices; retention screws hold the eyepieces in place, and independent focus adjustment can be made with each eyepiece. Also new is a zoom-lock, which allows you to lock the head at a specific magnification -- especially helpful for measurement applications. The redesigned nosecone features an integrated mounting-ring for ring-lights.
