The
CSL-312M can be used to provide a dynamic field of view control
between 2.8mm and 11.5mm focal lengths. It should be noted that
the picture will have an "artifically" wide field of view
with some curvarture of the video image for any focal length setting
wider than roughly 5.0mm. Unfortunately, there is NO way to provide
such a wide viewing angle without this type of distortion. The distortion
disappears when the lens is adjusted to a more narrow field of view.
This is a varifocal
zoom lens, and all lens adjustments must be made manually by hand.
Once the desired focal length is acheived, the lens has thumb screws
which tighten to maintain that specific focal length. We also carry
fixed focus C-mount lenses for those applications where desired.
The CSL-312M
has a manually adjustable iris control as well. This allows the
user to adjust the amount of light which passes through the lens
optical glass and reaches the imager for a specific amount of available
lighting. This lens also has thumb screws which tighten to maintain
a desired iris setting. When room illumination is likely to remain
constant, a manual iris lens in fact offers better overall image
quality in many situations than does an auto-iris lens. We do, though,
stock a similar lens with built-in auto-iris ability, our CSL-312A.
This lens has
a security-industry standard CS-mount lens thread, making it compatible
with the following Eyespyvideo.com models: TV-CSHRL,
TV-CSHR,
TV-CSHDN,
TV-BCSHR
, and TV-XCS.
