Using Manual Iris Lenses
Choosing the lens correctly is very important for mega-pixel cameras. Poorly
selected lenses may cause the image to appear blurry when the lens iris is fully
open or closed too much. To deliver sharp mega-pixel resolution images, it is
recommended to:
• Use mega-pixel-resolution lenses.
• Obtain best resolution and depth of focus by having the iris slightly closed.
When setting up the camera, direct the camera at the scene and try closing the
iris by several F-stops. At some point the image will look it s sharpest. Leave the
iris closed at this value.
Auto-Iris Lenses
Standard DC auto-iris lenses can be used with MP1, MP2 and M5 cameras
equipped with the auto-iris feature. CBC (America) recommends the following
high-resolution optics:
• Computar HG2Z0414FC-MP 4mm-8mm, format=1/2
Using Auto-Iris Lenses
MP1, MP2 and MP5 are available with DC auto-iris option. To use the DC auto-iris
lens:
1) Attach the lens to the MP camera.
2) Plug in the lens cable into the connector on the back of the camera. Make
sure that the lens cable is long enough. Many DC lenses are available with
short and long cable options.
The camera will automatically detect the presence of an auto-iris DC lens and
start using it. Auto-iris lens operation typically proceeds as follows:
• If illumination is sufficient, the camera will close the iris within half-a-minute.
• When the iris is closed, the image should become visibly sharper. As the iris
is gradually closed the image brightness may fluctuate slightly.
Monitoring Iris Status with CBC America Video System
You can monitor the state of the iris in CBC America Video System Settings
dialog. See Operating CBC America Video System for details.
