Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a lens unit and an imaging apparatus which can form a high quality image even when a temperature change occurs.SOLUTION: An object side light shielding member SH1 and an image side light shielding member SH3 are adhered to first and second lens arrays LA1 and LA2 so as to oppose the expansion toward the circumference direction from the center of the first and second lens arrays LA1 and LA2 and oppose the contraction toward the center direction from the circumference of the first and second lens arrays LA1 and LA2. Consequently, when the environment temperature is changed, expansion or contraction of the lens arrays can be regulated in both surfaces of the object side and the image side by the object side light shielding member SH1 and the image side light shielding member SH3. This configuration maximally suppresses deformation as a lens array laminate, and prevents the reduction of optical performance of a lens unit LH. Even when the temperature change occurs, the lens unit LH and the imaging apparatus can form a high quality image.
【課題】温度変化が生じても、高画質な画像を形成できるレンズユニット及び撮像装置を提供する。【解決手段】第1及び第2レンズアレイLA1、LA2の中心から周縁方向への膨張に逆らうように、かつ、第1及び第2レンズアレイLA1、LA2の周縁から中心方向への収縮に逆らうように、物体側遮光部材SH1及び像側遮光部材SH3が第1及び第2レンズアレイLA1、LA2に接着されているので、環境温度が変化した場合に、物体側遮光部材SH1と像側遮光部材SH3によりレンズアレイの膨張又は収縮を、その物体側と像側の両面で規制できるから、レンズアレイ積層体としての変形が極力抑えられ、これによりレンズユニットの光学性能の低下を抑制でき、温度変化が生じても、高画質な画像を形成できるレンズユニットLH及び撮像装置である。【選択図】図2 |
