Why Are There 3 Types of Naglers?

To achieve the full magnification range over 82° apparent field of view requires two types: Nagler Type-5 with focal lengths of 31, 26, 10, 16mm and Nagler Type-6 with focal lengths of 13,11, 9, 7, 5, 3.5, 2.5mm.  

The Type-5 permits the largest true field possible (31mm has 42mm field stop), while the shorter focal length Type-6 models are parfocal, with similiar size and weight and all with a comfortable 12mm eye relief.

The Type-4 models feature about 18mm of eye relief and with the \"instajust\" eyeguard are best for eyeglass wearers or Dioptrx users in their 22, 17, 12mm focal length range.
