An attachment system (10) for attaching a camera (14) to a microscope has a mounting structure for securing a camera above the eyepiece of the optical tube (16) of the microscope (18), and an adaptor (12) for providing a light shield extends between the lens opening of the camera and the optical tube. A downstream end (86) of the adaptor closely surrounds the outer periphery of the optical tube to prevent the undesired ingress of ambient light into the adaptor, while permitting relative movement between the adaptor and the optical tube. An illuminating system for a microscope employs a curved, transparent, light transmissive rod (20) having a light-receiving end surface (116), a light-receiving peripheral side (118) surface and a light emitting end surface (108). The rod is mounted with its light emitting end surface aligned with a passage extending through the stage (22) of the microscope upon which a specimen to be viewed and/or to be photographed is retained.

Un système de fixation (10) d'une caméra (14) à un microscope comprend une structure de montage qui permet d'assujettir une caméra au-dessus de l'oculaire du tube optique (16) du microscope (18) et un adaptateur (12) qui forme un écran anti-lumière et qui s'étend entre l'ouverture de l'objectif de la caméra et le tube optique. L'extrémité (86) en aval de l'adaptateur entoure étroitement la périphérie extérieure du tube optique, empêchant la pénétration indésirable de la lumière ambiante dans l'adaptateur, tout en permettant à l'adaptateur de se déplacer par rapport au tube optique. Un système d'éclairage pour microscopes utilise une tige translucide (20) courbe transparente ayant une surface terminale (116) de réception de la lumière, une surface latérale (118) périphérique de réception de la lumière et une surface terminale (108) de transmission de la lumière. Lorsque la tige est montée, sa surface terminale de transmission de la lumière est alignée avec un passage qui traverse la platine (22) porte-objet du microscope sur laquelle est retenu un échantillon à visionner et/ou à photographier.
