The 16mm Nagler Type 5 is a scaled down version of the "king of the field," 31mm. The Type-5 16mm is a smaller, lighter (0.45 lbs.), 1¼" only, 6-element design which replaces the 8-element 16mm Nagler Type 2. This exciting little high contrast eyepiece looks like a 19mm Panoptic, but packs the visual impact and sharpness we all expect from the 82° Nagler series. This eyepiece offers owners of 1¼" only scopes the largest possible true field in an 82° apparent field eyepiece. Great for small scopes and Bino Vues.
To achieve the full magnification range over 82° apparent field of view requires two types: Nagler Type-5 with focal lengths of 31, 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).
Type-6 models have shorter focal lengths, are parfocal, with similiar size and weight, and all with a comfortable 12mm eye relief.
The Type-4 models feature about long eye relief and with the "instajust" eyeguard are best for eyeglass wearers or Dioptrx users.
