Optical filters help to improve optical quality. They are provided with detailed technical parameters and have passed a strict quality assurance procedure.
The V38-lenses have a compact and robust metal mount, with precise irisadjustment and locking mechanism as well as a filter thread. With a special adapter the lenses can even be reversed for magnifying images.The lenses are available with focal lengths from 28 mm to 120 mm and coversensor diagonals from 30 mm up to 90 mm depending on the focal length. Their optical performance is optimized for typical working distances at machinevision applications.
The V38-lenses have no built-in focusing mechanism. Therefore a separatefocusing mount is needed. Schneider-Kreuznach is offering four focusing mounts with V38 interface:
UNIFOC 12 V38/V38 17.4-29.4 mm
UNIFOC 7 V38/V38 20-27 mm
UNIFOC 7 V38/M58x0.75 20-27 mm
UNIFOC 5 V38/C 19.2-24.2 mm
We also offer a larger UNIFOC 25 for situations where smaller UNIFOCs may cause vignetting when used with large sensors. Special adapters are available for the V38 system.
The V38-lenses have no fixed back focal lengths and also cameras differ in theirflange-to-image distances. Therefore the extension length of the lenses must beadapted individually to the current image task. This is done by extension tubes,which can be combined in different lengths. They are installed between lens and camera. Extension tubes are available in different sizes.
Special camera adapters are available that connect the V38-Mount-Systeminterface to a variety of camera mounts. Types and extensions are shown below.
