Abstract
(EN)
In order to provide a coaxial lighting device with which a field of view can be widened, while being compact, and with which an adjustment operation can be made simple, this coaxial lighting device is provided with a half mirror 1 disposed obliquely on an observation axis A1 joining a workpiece W, which is an observation target, and an observation unit M for observing the workpiece W, a light source 2 which radiates light onto the half mirror 1 from a direction different to the observation axis A1, and which is disposed in such a way that light reflected by the half mirror 1 is radiated onto the workpiece W, a lens 3 provided between the half mirror and the workpiece, and a first aperture 4 provided between the light source 2 and the half mirror 1, wherein the first aperture 4 is disposed at the focal point of the lens 3 on a radiation axis A2 joining the light source 2 and the half mirror 1.

Afin de fournir un dispositif d'éclairage coaxial compact avec lequel un champ de vue peut être élargi et avec lequel une opération de réglage peut être simplifiée, ce dispositif d'éclairage coaxial est pourvu d'un demi-miroir 1 disposé obliquement sur un axe d'observation a1 joint à une pièce W constituant une cible d'observation, et une unité d'observation M pour observer la pièce W, une source de lumière 2 qui émet de la lumière sur le demi-miroir 1 à partir d'une direction différente de l'axe d'observation A1, et qui est disposé de telle sorte que la lumière réfléchie par le demi-miroir 1 est émise sur la pièce W, une lentille 3 disposée entre le demi-miroir et la pièce, et une première ouverture 4 disposée entre la source de lumière 2 et le demi-miroir 1, la première ouverture 4 étant disposée au point focal de la lentille 3 sur un axe de rayonnement A2 joignant la source de lumière 2 et le demi-miroir 1.
