3.4

Operating principle

The LED lamp is very similar to a point light source.
The light is propagated through the optical cable and directed to the field
of view (operative field).
3.4.1

Brightness control

The brightness is adjusted in increments (5 % increments) via the bright-
ness control 4.
If a camera system with auto light quantity control is connected via the
communication interface cable OP942, the light intensity can be con-
trolled via the camera.
When the brightness control 4 is adjusted during active auto light quan-
tity control, the system is immediately switched to manual mode and the
light intensity is displayed in %.
3.4.2

Activation/standby mode

On pressing the brightness control with push function 4, the active light
source is put into standby mode. On pressing the brightness control with
push function 4 again, the light source goes back to the previously set
value.
If a camera system with auto light quantity control is connected via the
communication interface cable OP942, the LED light source can also be
activated or deactivated via the camera.
3.4.3

Multi optical cable socket

Various optical fiber cables from Aesculap/Storz, Olympus and Wolf with
an active diameter of 3.5 mm or 4.8 mm can be plugged into the multi-
optical cable socket 7.
3.4.4

Light source test unit with sterile adapter

The optical cable test unit can be used in the sterile field with a sterile
adapter OP941.
The optical cable test unit is used for testing the light transmission of the
4.8 mm optical fiber cable connected in each case.
The testing of 3.5 mm optical fiber cables causes false measurement
results.
