10x eyepieces are standard; eyepiece magnifications of 16x and 25x are intended for special applications only. All eyepieces have removable or fold-down eyecups and can be used with or without eyeglasses.
Eyepieces identified with M are equipped with a focusing eyelens for dioptric equalization (from –6.8 to +4.2 or –6 to +5) and graticule holder. The external diameter of the eyepieces is D = 30 mm.
The graticule diameter is D = 26 mm. Specifications are engraved on the eyepiece, e.g. HC PLAN 10x/20 M. HC PLAN = correction type, 10x = magnification/20 = field number FOV, = for eyeglass wearers (high exit pupil), M = dioptric adjustment/graticule holder.
