- レーザ光を基端部から内部に導入される光ファイバと、前記光ファイバの先端部に設けられ、前記レーザ光を照射されて拡散光を射出する発光部とを備えた光源装置と、
先端面の形状が凸状である光伝達素子と、
その光伝達素子の基端側所定位置に前記発光部を固定結合するための結合部材とを備えてなり、
前記光伝達素子が、前記所定位置に固定された前記発光部からの拡散光のうち、光軸から一定角度の範囲内で拡がる光については直接その先端面に到達させ、また前記一定角度よりも拡がる光については側周面で内方へ全反射させた後、前記先端面に到達させ、そこから所定の集光位置に向かって収斂するように外部に射出する透明体で形成されたものであることを特徴とする光射出装置。
