| abstract | 【Task】 Provided is an optical filter having an infrared shielding function and an ND function, which suppresses warpage and waviness, has good adhesiveness, and has a small change in transmittance over time. [Solution] In the optical filter of the present invention, an ND film and an infrared shielding film having different stress directions are formed in this order, and a stress buffer film is provided between the ND film and the infrared shielding film. The stress buffer film is a metal film or a gradient film whose composition continuously changes. An optical filter may be used in the light quantity adjusting device. The light amount adjusting device may be used for the image pickup device. [Selection diagram] Figure 1 |
