Powerful Clear Zoom
SAMSUNG AUTO IRIS LENS FOR CCD CAMERA OPERATING
INSTRUCTIONS
The SLA-880 is a CCD camera lens with automatic iris function, electronically
controlled by video signals, and optical 10x zoom. Distant objects can be zoomed in
and focused for clear images with a simple operation of a switch. The photometric
system, designed to provide continuous adjustable readings between peak and
average values, provides optimum image quality even in conditions where the
contrast of the object changes in a wide range. When power is cut off, the iris is
automatically closed to protect the product from strong light.

2) Operate the Focus switch to focus on the object.
3) Move the zoom to extremely Wide position, and make sure to find the
clearness of the image.
4) Again move the zoom to get the view angle of the desired object.
* Even after the process of(1) to (3), if the image is not clear, it may be necessary to
adjust the Flange back of the camera.
3. Adjustment of Automatic Iris System
1) Light Metering Method (ALC)
It is alllowed variable selections of light metering between average and peak by
adjusting ALC potentiometer. ALC potentiometer is set at Average position at
shipment. The method of ALC adjustment is as follows.
Take off the ALC-cap on the lens cover and turn the ALC potentiometer with(-)
precision screw driver until suitable exposure is obtained.
2) Image Signal Level Adjustment (LEVEL)
Image level of video signal can be readjusted by turning the Level Potentiometer when
necessary according to the characteristics of the camera and the light conditions of the
objects. It is normally unnecessary to make sensitivity adjustment, since the video signal
level is set to an appropriate value at shipment. The method of readjustment, if necessary,
is as follow. Take off the Level-cap on the lens cover and turn the Level Pot. with(-)
precision screw driver so that an optimum level is obtained.

For the flauge back adjustment, follwing procedure is recommended.
Set up object or a test pattern about 25 meters or more away from the camera.
Keep the iris open fully. For the AI Lens, reduce the illumination or apply a neutral
density filter in front of the lens. Or, if possible, supply DC8.5~16V power between
Vcc(+) [red] and Vcc(-) [black] without connection of Video signal [white]. At the time if
the image on the monitor is too bright, use ND Filter in front of the lens to reduce the
light to come in.
Turn the focus to extremely far position.
Turn the zoom extremely to wide position. Then observe the image on the monitor
whether it is clear.
If it is not clear, adjust flange back length of the camera by turning flange ring or
moving image sensor of the camera.
Turn the zoom extremely to tele position. Then observe the image on the monitor
whether it is clear.
If it is not clear, turn the focus to get best focus.
Repeat the process
to
until you get clear focus all the way through the zoom range.
Getting clear focus, please fix the flange ring or image sensor of the camera. The
flange back of C-mount is fixed to 17.526mm.

5. Angle of View
It is important to know the angle of view of the lens to take in the object. Angle of view
changes with focal length of lens and image size of camera. The focal length to cover
the object can be calculated from the next formula.
* Formula for calculation
f : focal length of lens
V : Vertical size of object
H : Horizontal size of object
D : Distance from Lens to Object
v : vertical size of image
h : horizontal size of image
