Abstract: An imaging device of the present invention includes an image capturing unit, a noise obtaining unit, a fixed noise calculating unit, and a noise eliminating unit. The image capturing unit generates image data by photoelectrically converting, pixel by pixel, a subject image formed on an available pixel area of a light-receiving surface. The noise obtaining unit reads a noise output from a partial area of the available pixel area. The fixed noise calculating unit calculates an estimation of fixed pattern noise of the available pixel area based on the noise output read from the partial area. The noise eliminating unit subtracts the fixed pattern noise from the image data.

Abstract: A film of aluminum 2 is formed on a glass substrate (BK7) 1 by vacuum evaporation, and a multilayer optical thin film 3 is formed by an ion sputtering method on this aluminum film 2. Afterwards, such a member is cut into small pieces by means of dicing, and the aluminum 2 is then etched by a sodium hydroxide solution, so that the glass substrate 1 and the multilayer optical thin film 3 are separated. When the aluminum thickness exceeds 90 nm, clouding occurs in the multilayer optical thin film 3, and when the aluminum thickness is less than 10 nm, the separation of the glass substrate and multilayer optical thin film cannot be performed cleanly. Accordingly, the aluminum thickness is set in a range of 10 to 90 nm.
