This is a professional grade binocular stereo microscope with 10X and 30X magnification settings. It incorporates all the most excellent features of a high quality laboratory instrument. Designed to meet the demands of modern professional microscopy applications, this microscope exceeds all expectations. The versatile illumination system with the microscope provides both incident (top) lighting and transmitted (bottom) lighting with intensity controls. The top lighting shining down onto objects is used for the observation of surface details and fine structures of three-dimensional objects. The transmitted illumination through the frosted stage plate is for the observation of the objects that allows light to get through them, like slides, diamond, etc..
