PRELIMINARY
4.2 Lenses
The 2K and 4K TDI cameras as shipped from the factory accept M58 optical components
with M58 threads. The 4K TDI camera only accepts M58 lens types. A sample lens system
for 256 DPI would include the following:
40mm lens, Schneider P/N 25-014798
Folus Mount, Schneider P/N 21-013048
Adapter, Schneider P/N 25-020054
When the lens mount (lens extender tube and its lock ring) is removed, the front surface of
the camera is seen as a square with a large threaded hole in the center. The "z" distance
from the surface of the square to the top of the sensor is 10.0mm. For the 256 DPI
example above, the “Free and Clear” distance between the camera and object is 393mm.
