Device Description

The C-Mount HD Optical Zoom Coupler, hereafter called "video lens", can be used
in laparoscopy, arthroscopy and hysteroscopy procedures.
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.
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!
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

Selecting the Focal Length

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").
