Title
(EN) LENS ARRANGEMENT
(FR) AGENCEMENT DE LENTILLE
Abstract
(EN) A lens arrangement suitable for looking through small holes is provided in which no conventional integral physical lens stop is required. The lens arrangement is relatively insensitive to its position, meaning that it may be set back behind the hole reducing the risk of detection and allowing rapid installation.
(FR) L'invention concerne un agencement de lentille qui convient pour regarder à travers de petits trous dans lequel aucune butée de lentille physique intégrale classique n'est requise. Cet agencement de lentille n'est relativement pas sensible à sa position, en ce sens qu'il peut être fixé derrière le trou, réduisant ainsi le risque de détection et permettant une installation rapide.
