It includes a pair of super widefield high-eyepoint 10X eyepieces and foldable eyeguards. It comes with 45-degree inclined 30mm eyetubes with diopter. Its trinocular port enables to add photo or video capability. The microscope provides sharp clear erect stereo images over a large zoom magnification range. Its super widefield optics and high-eyepiont design ensure an easy and comfortable observation. This microscope head fits all the stands with a 3" (76mm in diameter) O-ring holder.
