Our precision objectives feature optical designs well corrected for infinite conjugate with the added benefit of a working distance more than 5 times as long as ordinary microscope objectives. This long working distance makes these lenses useful where other objectives are prohibited by mechanical constraints.

These objectives are excellent for laser collimating and focusing applications. The optical designs and antireflection coatings are optimized for 400–700 nm for the visible objectives, and 800–1300 nm for the near-IR objectives. The exception is N-20X-APO-IR, which is designed to provide a constant focal length over the 800–1500 nm range.
