Abstract

광원으로부터 발산되는 광빔을 단면이 진원인 동시에 광축에 평행한 평행빔으로 정형하는 빔정형 콜리메이터(beam shaping collimator)가 개시되어 있다. 개시된 콜리메이터는 입사하는 빔의 단면을 타원에서 원형으로 정형하는 기능과 그 정형된 원형의 빔을 평행하게 출사시키는 두 가지 기능을 발휘한다. 이를 위하여 수직 및 수평방향으로 굴절률이 다르게 설계되는 입사면과 출사면을 가진다. 그 입사면과 출사면의 곡률반경은 입사하는 빔의 발산각과 이에 따른 수직 및 수평 방향의 각 촛점거리에 따라 결정된다. 두가지 기능을 동시에 발휘하므로 빔정형 및 평행빔을 위한 광학장치의 원가절감 등에 기여한다. ＜제 7 도 (가)(나)＞A beam shaping collimator is disclosed for shaping a light beam emitted from a light source into a parallel beam parallel to the optical axis while having a circular cross section. The disclosed collimator has two functions of shaping the cross section of an incident beam from an ellipse to a circle, and outputting the shaped circular beam in parallel. To this end, it has an entrance face and an exit face that are designed with different refractive indices in the vertical and horizontal directions. The radius of curvature of the incident surface and the exit surface is determined according to the divergence angle of the incident beam and the respective focal lengths in the vertical and horizontal directions. Both functions simultaneously contribute to the cost reduction of optical devices for beam shaping and parallel beams. <Figure 7 (a) (b)>
