An optical instrument (10) for use in collecting light from an object (44), the optical instrument (10) having a post-objective waist (34) with a variable optical filter (32) positioned approximately at the post-objective waist (34). The optical instrument (10) for collecting light from the object (44), comprising an objective lens (18) positioned to receive light from the object (44), an exit lens (24) positioned to focus the light at a focal position (26), and a variable optical filter (32) positioned between the objective lens (18) and the focal position (26) approximately at a waist (34) of the light. The optical instrument (10) may be an epifluorescence microscope (12) for use in observing an image formed from light from an object (44) under illumination by a light source (14). The variable optical filter (32) may be a circular variable interference filter or a tilting interference filter.
L'invention concerne un instrument optique (10) pour capter de la lumière émanant d'un objet (44), qui comprend une taille post-objectif (34) muni d'un filtre optique variable (32) placé approximativement au niveau de la taille post-objectif (34). Ledit instrument optique (10) comprend un objectif (18) orienté pour recevoir la lumière émanant de l'objet (44), un oculaire (24) orienté de manière à concentrer la lumière sur un point focal (26), et un filtre optique variable (32) placé entre l'objectif (18) et le point focal (26), approximativement au niveau d'une taille (34) de la lumière. Ledit instrument optique (10) peut être un microscope à épifluorescence (12) qu'on utilise pour observer une image formée à partir de la lumière émanant d'un objet (44) illuminé par une source de lumière (14). Le filtre optique variable (32) peut être un filtre interférentiel variable circulaire ou un filtre interférentiel basculant.
