This eyepiece is designed for MAGUS microscopes. It provides 20x magnification and can be used with 4x, 10x and 20x objectives. The special feature of this eyepiece is the diopter adjustment ring, with which the user can adjust the focus to his vision. When using the eyepiece with a microscope with diopter adjustment, focus can be adjusted in two ways. The MAGUS MD20 20x/12mm eyepiece is housed in a 30mm diameter eyepiece tube. The eye distance is sufficient to observe with glasses.
