Zusammenfassung:To provide a luminaire and an imaging apparatus that can achieve at least one of an increase in light reception quantity of a camera sensor or a decrease in lighting light quantity drift, and reduction in lighting unevenness.SOLUTION: A luminaire 1 according to the present invention comprises: a plurality of light sources 10 which are linearly arrayed side by side; a cylindrical lens 30 which extends in the array direction of the plurality of light sources 10 to cover the plurality of light sources 10; and a cylindrical lens array 20 which includes a plurality of micro cylindrical lenses 21 arrayed in the array direction between the plurality of light sources 10 and the cylindrical lens 30, wherein the micro cylindrical lenses 21 converge lighting light L10 that the light sources 10 emit in the array direction, and the cylindrical lens 30 converges the lighting light L10 in a direction orthogonal to the array direction.SELECTED DRAWING: Figure 1 【課題】カメラセンサの受光量の増加、照明光量ドリフトの低減の少なくともいずれかと、照明ムラの低減を達成することができる照明装置及び撮像装置を提供する。【解決手段】本発明に係る照明装置1は、ライン状に並んで配列された複数の光源10と、複数の光源10を覆うように、複数の光源10の配列方向に延びたシリンドリカルレンズ30と、複数の光源10と、シリンドリカルレンズ30との間において、配列方向に配列された複数の微小シリンドリカルレンズ21を含むシリンドリカルレンズアレー20と、を備え、微小シリンドリカルレンズ21は、光源10が生成した照明光L10を配列方向において集光し、シリンドリカルレンズ30は、照明光L10を配列方向に直交した方向において集光する。【選択図】図1
