3.1 Device Description
The C-Mount HD Optical Zoom Coupler, hereafter called "video lens" , can be used
in laparoscopy, arthroscopy and hysteroscopy procedures.
Properties of the video lens The lens has a focal length range of 14 mm to 29 mm. This allows the user to
choose a circular or a full screen depending on the diameter of the endoscope.
Interfaces/Ports The video lens is designed for the use of endoscopes with a proximal end in ac-
cordance with DIN 58105 and endoscopic cameras with a C-mount connection
according to SMPTE 76 / ISO 10935.
CAUTION!
Do not use an endoscope with a proximal interface that does not comply with
the currently valid version of the standard DIN 58105!
CAUTION!
Do not use an endoscopy camera with a distal interface that does not comply
with the currently valid version of the standard SMPTE 76 / ISO 10935!
Design of the video lens The video lens consists of three control elements:
• Quick-release coupling for connecting with the endoscope
• Focus adjustment ring to focus the desired lens level
• Zoom adjustment ring to change the desired image size
3.1.1 Selecting the Focal Length
Zoom function The focal length of the video lens determines the size of the image that is dis-
played on the monitor. The focal length of the video lens is changed by using the
zoom ring (3), (Fig. 3-1 "Design of the video lens").
When using a short focal length, the entire endoscopic image information is de-
picted in a circular display (Fig. 3-2 "Circular depiction with short focal length").
