    • On the light-entering surface side of a base material 10, a coating layer 11 in which a high-refractive layer and a low-refractive layer are sequentially disposed alternately on one on the other is provided for blocking infrared radiation. One of the high-refractive layers is configured by an ITO film 11a so that the conductivity is increased on the surface of the coating layer. Herein, in view of preventing, to a further extent, the attachment of dirt and dust by providing the conductivity to the surface of the coating layer, it is desirable if the outermost high-refractive layer is made of a transparent conductive material. Moreover, it is desirable if the total layer thickness is 140 nm or smaller for the refractive layers formed outside of the high-refractive layer made of the transparent conductive material.
    • 在基材10的光入射表面侧,设置有高折射层和低折射层相互交替排列的涂层11,用于阻挡红外辐射。 高折射层之一由ITO膜11a构成,使得在涂层的表面上导电性增加。 这里,考虑到通过向涂层的表面提供导电性来进一步防止污物和灰尘的附着,所以最理想的是,最外面的高折射层由透明导电材料制成。 此外,对于由透明导电材料制成的高折射层外侧的折射层,总层厚度为140nm以下是理想的。

    • An image pickup apparatus includes a controlling unit moving an electronic front curtain in a simulated manner from an exposure start position towards an exposure end position by successively performing reset operations on a plurality of pixels in an image pickup element in a predetermined direction; a rear curtain that moves from the exposure start position towards the exposure end position by a biasing force of a biasing unit; and a storage unit storing data indicating a change in movement characteristics of the rear curtain with time. On the basis of the data, the controlling unit changes movement characteristics of the electronic front curtain in accordance with the change in the movement characteristics of the rear curtain with the time.
