Claims (2)
- 光源と、
該光源からの光を少なくとも透過させる光学部材と、
それぞれ前記光源よりも前記光学部材側に延び、該光源からの光を反射して前記光学部材に入射させる第1の反射部と第2の反射部を含み、該第1及び第2の反射部の間に前記光を通過させる開口を有する反射部材とを有し、
前記光学部材の光入射側の面における前記開口に面する領域よりも外側の領域に、前記第1及び第2の反射部の端部から離れるように凹んだ凹部が形成されており、
前記凹部は、前記光源からの光のうち前記反射部で反射されずに前記光学部材の外部から該凹部に入射した光を、前記光学部材の射出面に向けて屈折させる屈折面と、前記光源からの光のうち前記反射部で反射されずに前記光学部材の内部から該凹部に入射した光を、前記射出面に向けて反射する反射面と、を含み、
2つの前記凹部を含む断面において、前記凹部は、前記開口に面する領域側に前記屈折面と前記反射面とを有することを特徴とする照明装置。 - 請求項1に記載の照明装置を有し、
該照明装置からの光によって照明された被写体を撮像することを特徴とする撮像装置。
