Navitar : 59-LGN-705
Description
Navitar’s 59-LGN-705 ELWD (Extra-Long Working Distance) Macro Invaritar telecentric gauging lenses provide exceptional imaging performance and are the best choice for machine vision applications where an extra-long working distance is required.
The 59 LGN 705 Telecentric performance (<0.1° chief ray angle over the entire object field) allows precise gauging of 3-dimensional objects. Low distortion (<0.5% over the entire object field) provides highly accurate images.
Features
