The 12.5x magnification eyepiece is designed for 4x, 10x, 20x, 40x, 60x and 100x magnification objectives. The eyepiece is housed in a tube with a diameter of 30 mm. This model has a diopter adjustment ring to compensate the user's vision. This means that the eyepiece can be used with microscopes that do not have an adjustment ring on the eyepiece tube. If the microscope has such a mechanism, the focus can be adjusted either on the eyepiece or on the microscope. The eye distance of 10 mm enables comfortable observation with glasses.
