Description
しかしながら、上述のストロボ装置9では、屈折力の強い光学部材11を採用すると、図4(b)に示す如く、光の照射領域が過度に拡張される結果、撮像する対象とする領域外にも光を照射してしまう場合がある。このような場合、上述のストロボ装置9は、撮像する対象とする領域全体を適正な光量の光で照らすことができないことがある。
前記光源2及び前記反射面4の少なくとも何れか一方と光学部材3とが光軸Aが延びる方向(以下、光軸A方向とする)に沿って相対変位可能になっている。本実施形態では、光源2がリフレクター5の反射面4に対して変位するようになっている。
2 光源
3 光学部材
4 反射面
5 リフレクター
6 特定反射域
7 第一反射面(反射面の特定反射域を境とする光学部材とは反対側の面)
8 第二反射面(反射面の特定反射域を境とする光学部材側の面)
A 光軸
Claims (1)
- 一方向に長手をなす、撮像装置が撮像する領域に光を照射する光源と、該光源と平行で該撮像する領域側に配置される光学部材と、前記光源の長手方向に沿って長手をなすとともに、前記光源からの光を前記光学部材に向けて反射する反射面を有するリフレクターとを備え、前記光源及び前記反射面の少なくとも何れか一方と光学部材とが、前記光源の長さ方向に直交し光源からの光が前記撮像する領域に向かう照明光軸方向に沿って相対変位可能なストロボ装置であって、前記反射面は、前記光源が前記反射面から前記照明光軸方向に最も離れた状態における反射光のうちの前記光学部材の中心に向けて反射される光と前記反射面とが交わる前記反射面上の特定反射域よりも前記光学部材とは反対側に位置する第一反射面と、前記特定反射域よりも前記光学部材側に位置する第二反射面とを有し、前記第一反射面は、内側に曲率中心を有して凹状に湾曲し、前記第二反射面は、外側に曲率中心を有して前記光学部材に近づくにつれて前記照明光軸中心から離間するように湾曲することを特徴とするストロボ装置。
