N-LASF9 Ball Lenses

  • High Index for a Closer Focal Distance
  • High Tolerance

The use of high index glass results in a decrease of the back focal length. Shorter distances simplify fiber coupling. This matrix also has the same improved tolerancing as our High Tolerance matrix.

For general information about ball lens, as well as how to calculate the NA and Focal Length, view Understanding Ball Lenses.
