Abstract
A draft Standard for Passive, Hand-Held Night Vision devices has been developed for the Law Enforcement Standards Laboratory of the National Bureau of Standards. This Standard is now being circulated for comment prior to adoption as a Standard of the National Institute of Law Enforcement and Criminal Justice of the Law Enforcement Assistance Administration of the Department of Justice. The paper mentions some of the philosophy behind the standard, lists the performance requirements and describes briefly the test procedures for (A) focus adjustment, curvature of field and distortion of the eyepiece lens, (B) optical gain, optical gain stability, light equivalent background, light induced background, luminance of output screen, luminance uniformity, cathode and screen quality, contrast transfer function, distortion and flare of a night vision device complete with objective lens, but with the eyepiece removed, and (C) for resistance to vibration, high and low temperature storage, operation and thermal shock and humidity of night vision devices complete with both objective and eyepiece lenses, and (D) boresight adjustment, click movement and resistance to mechanical shock of night vision devices intended for use as rifle sights.
