Eyepiece Setting for the L1A1 Weapon Sight.

Abstract

Three experiments were performed in order to examine the suggestion that relatively high negative settings (-1,75 to -2.00 dioptres) of the L1A1 image intensifier eyepiece yield optimum visual performance. Although detection and recognition performance did not vary greatly as a function of the eyepiece settings (10% or less), the data suggest that the traditional setting of -0.5 to -1.0 dioptres be used. The relatively large advantage to be gained from selecting the user of the L1A1 is noted. (Author)
