Colposcope – 5 Step Magnifications/Excellent Vision

YZH-5FRB

 

Colposcope: A lighted magnifying instrument used by a gynecologist to examine the tissues of the vagina and the cervix. The procedure is called colposcopy. The colposcope is used by doctors to perform a colposcopy examination. This examination examines the cervix and vagina, and is often used to detect cervical cancer and immunosupression such as HIV infections.

YZH Series Colposcopes adopts infinite microscopic principle, which provides the possibility of extending the function of the instrument. The stereo microscope incorporates converging binocular tubes to allow the natural stereoscopic vision. A 8°-10° convergent optical system gives the most comfortable vision to achieve binocular images
