るビデオカメラ用プラスチックレンズ。In a video camera lens that uses a plastic lens for part or all of the lens system, the movement of the image plane due to changes in the shape and refractive index of the plastic lens due to temperature can be avoided by moving the image plane according to the temperature. For a video camera, the imaging element is attached to the lens through an element whose shape changes greatly in response to temperature changes by laminating two types of metals with different coefficients of thermal expansion, like insect trapping. plastic lens.
