Abstract

Cette invention concerne un dispositif d'éclairage et un système d'éclairage pour microscope. Le corps (1) du dispositif d'éclairage (100) consiste en une forme cylindrique à échelons. Une source lumineuse (4) à diode électroluminescente (DEL) est montée sur l'extrémité supérieure du corps (1), une pièce de montage (1c) à fixer sur le tube porte-oculaire (21) du microscope (200) est installée sur l'extrémité inférieure du corps et une plaque de polarisation intégrée y est installée. La pièce de montage (1c) destinée au corps (1) du dispositif d'éclairage (100), à l'endroit où le diamètre est le plus faible, est insérée et ajustée dans un tube porte-oculaire (21) du microscope (200). Un couvre-plaque de polarisation (8) est installé pour protéger l'autre tube porte-oculaire (21) du microscope (200). Ceci assure la fabrication économique et la compacité du dispositif d'éclairage, qui permet des observations avec illumination verticale et coaxiale.
