It comes with two eyepieces with four magnifications; in the axis of the optics is the direct eyepiece with magnifications for panoramic vision of 1X and colposcopic of 20X and of contact of 60X magnification. Another lateral eyepiece for cellular vision in vivo at 150X of magnification.
Currently, a 30 cm long endoscope is also available. With a single direct eyepiece with a panoramic view of 1X and an in vivo cell vision of 80X, with zoom it can reach up to 100X, with a diameter of 3 mm and a 4 mm diagnostic sleeve. This endoscope is frequently also used for hysteroscopy
