Available in different focal lengths, these fittings connect the endoscope to an endoscopy camera equipped with a “c” mount. The choice of focal length is made according to the size of the image to be reproduced on the screen. For example, in hysteroscopy is desirable to view the entire round image in order to keep the orientation index of the optics under control. The AD32 is the best choice for coupling the EP10, EP20 and AC2 systems to the HD29 hysteroscope. For the same purpose, the AD25 fitting is mainly used on EV3 cameras. The variable focal length of the ADZ zoom fitting is useful when you want to use the same camera for both hysteroscopy and colposcopy.
