Abstract: An object of the invention is to provide an endoscope system capable of easily measuring the size of a subject. In an endoscope system related to one aspect of the invention, since an index figure indicating an actual size of a specific region of a test object is displayed together with an image of the subject, a user can measure the specific region easily by comparing the specific region with a marker. Since the size of the index figure is set in accordance with a spot position, there is no need for distance measurement, a device configuration is simple, and measurement can be quickly and easily performed. In addition, a specific value of the “actual size” can be set in accordance with conditions, such as the type of test object and the purposes of measurement. Additionally, an affected region can be the specific region in a case where the test object is a living body.

Abstract: The antireflection film is provided on a surface of a light-transmitting substrate and includes a thin multi-layer film and a fine unevenness layer that are laminated in this order from the substrate side. The thin multi-layer film includes multiple layers. The fine unevenness layer has a structure in which an uneven structure having a shorter average pitch than a wavelength of used light is provided and in which a refractive index to the used light changes continuously depending on a continuous change in a space occupation of the uneven structure in a thickness direction of the thin multi-layer film. The multiple layers include: an oxide film having a relatively high refractive index that is formed of at least two metal elements or is formed of silicon and at least one metal element; and an oxynitride film having a relatively low refractive index.
