The optical aiming device may be mounted on firearms. It comprises a light-collecting rod (8) consisting of a phosphor material to illuminate a central circular spot (22) of an aiming mark (6). Such illumination passes through a truncated hollow cone (25) and is used for good ambient light conditions. For poor ambient light four tritium luminous cells (18, 19, 20, 21) are mounted around the truncated hollow cone (25). Each tritrium cell illuminates one radial line component (23) of the aiming mark (6) via the external mirrored lateral area of cone (25). To adapt the brightness of the aiming mark to the brightness of the target the tritium luminous cells (18, 19, 20, 21) may be shifted on a circle around cone (25) with respect to the line components (23) of aiming mark (6).
