Features
Telecentric performance (<0.1° chief ray
•
angle over the entire object fi eld) allows pre-
cise gauging of 3-dimensional objects.
Low distortion (<0.5% over the entire object
•
fi eld) provides highly accurate images.
Long working distance permits convenient
•
mounting.
Rugged single-piece design stands up to harsh
•
industrial environments.
Lockable aperture adjusts to select the required
•
depth of fi eld.
Standard C-mount camera interface.
