A modular laser objective for use with a microscope is provided. A mounting modular body per-mits the modular objective to be releasably mounted to the turret of a microscope. The objective has an optical axis that permits an image beam to be emitted through the ob-jective toward the eyepiece of a microscope. The modular body supports a mirror positioned at an angle to the opti-cal axis of the objective. A modular laser assembly is mounted on the modular body on a first side of the mirror for directing a laser beam toward the mirror so that the en-ergy is reflected off the mirror and through the objective in a direction that is substantially aligned with the optical axis of the objective. A modular indicator assembly is re-ceived in the modular body and includes a source of light positioned with the light incident on the other side of the mirror to reflect a beam of light in a direction opposite to the direction of the laser beam to provide an optical repre-sentation at the eyepiece of a microscope or on a camera of the position on the target of the laser beam being emit-ted by the objective.

La présente invention concerne un objectif laser modulaire prévu pour être utilisé avec un microscope. Un corps modulaire de support permet de monter lobjectif modulaire de manière libérable sur la tourelle dun microscope. Lobjectif comporte un axe optique qui permet lémission dun faisceau dimage via lobjectif en direction de loculaire dun microscope. Le corps modulaire supporte un miroir positionné de manière angulaire par rapport à laxe optique de lobjectif. Un ensemble laser modulaire est monté sur le corps modulaire sur un premier côté du miroir pour diriger un faisceau laser en direction du miroir de telle sorte que lénergie est réfléchie à partir du miroir et traverse lobjectif dans un sens sensiblement aligné par rapport à laxe optique de lobjectif. Un ensemble indicateur modulaire vient se loger dans le corps modulaire et comprend une source de lumière positionnée de telle sorte que la lumière soit incidente sur lautre côté du miroir pour réfléchir un faisceau lumineux dans un sens opposé au sens du faisceau laser pour assurer une représentation optique, au niveau de loculaire dun microscope ou sur un appareil photo, de la position sur la cible du faisceau laser émis par lobjectif.
