A fundus optical image device includes a light source, a first optical element set and a second optical element set. The first optical element set includes a first diaphragm. The light of the light source passes through the first diaphragm and enters into a fundus through the first optical element set. The second optical element set includes a second diaphragm. The light of the light source is reflected by the fundus and then passes through the second diaphragm to present an image of the fundus. One of the first diaphragm and the second diaphragm is a micro array diaphragm.一種眼底光學影像裝置包含一光源、一第一光學元件組以及一第二光學元件組。第一光學元件組包含一第一光圈，光源之光線係穿過第一光圈並經由第一光學元件組入射至一眼底。第二光學元件組包含一第二光圈，光源之光線係經眼底反射並穿過第二光圈以呈現眼底之一影像。其中，第一光圈及第二光圈的至少其中之一係微陣列光圈。
