An apparatus and method of manufacturing a sighting device mountable to a gun to assist a shooter in aiming at a target. The apparatus comprises an optical element and a light source which provide feedback to the user regarding alignment with a target. The alignment aid optical element is a ring of transparent material with a user-facing, contoured surface with an inner and outer edge. The contoured surface is coated with a reflective material that reflects a narrow band of light wavelengths. The apparatus further comprises a light source coupled to a mount located at a focal point of the lens wherein the emission of light from the light source faces the lens. The wavelengths emitted from the light source correspond to those of the coatings on the lens.

In the present application, a sharp visible light transmission band can be obtained while efficiently and accurately blocking ultraviolet light near the short-wavelength visible light region and infrared light near the long-wavelength visible light region, and the ripple phenomenon can be minimized regardless of the incident angle. It is possible to provide an optical filter capable of obtaining high visible light transmittance while securing the above characteristics even in the case where a near-infrared absorption glass is used as a substrate.

The present disclosure provides for articles that can exhibit structural colors through the use of an optical stack and a cover release layer, where the cover release layer is disposed on an externally (or outwardly) facing surface of the optical stack. The optical stack can be disposed on a substrate, which can be disposed on a surface of an article or the optical stack can be disposed on a surface of the article. The cover release layer can be disposed on the optical stack on the side opposite the substrate or article surface so it is on the externally facing surface and can be viewed by an observer. When exposed to visible light, the optical stack imparts a structural color, where the structural color is visible color produced, at least in part, through optical effects (e.g., through scattering, refraction, reflection, interference, and/or diffraction of visible wavelengths of light). The structural color can have a single color or be multicolor, including iridescent. The cover release layer is disposed over (e.g., at least portions) of the optical stack so that the structural color is not present since it is not exposed to light, but when the cover release layer is removed, the optical stack can impart structural color. The cover release layer can be removed by abrasion (e.g., intentional or unintentional), where the abrasion can be applied to the cover release layer that causes separation of the cover release layer from the optical stack.
