Abstract
A semitransparent mirror is attached to a holder on its objective side and an LED (light source) is attached to the holder on its ocular side. The light from the LED is reflected by the semitransparent mirror and provided as an aiming point. A receiving recess having an inclined axis is formed in one end of the holder on the objective side. A resilient ring, the semitransparent mirror and a support ring are received in the receiving recess in this order. Three or more adjusting screws are equally spacedly arranged in the circumferential direction. By selectively tightening the adjusting screws, the inclination of the semitransparent mirror is adjusted.
