An optical flare is observed in IRAS 01003-228, [7] [8] with a luminous one recorded in June 2010. [8] Since both helium emission lines are detected in the galaxy following the optical flare, the most likely explanation is a candidate tidal disruption event, where a star wandering close to the black hole is ripped apart by tidal forces.

Lens flare on Borobudur stairs to enhance the sense of ascending. A lens flare is often deliberately used to invoke a sense of drama. A lens flare is also useful when added to an artificial or modified image composition because it adds a sense of realism, implying that the image is an un-edited original photograph of a "real life" scene.
In 2002, PKS 0736+017 exhibited multiple variability behaviors. During most nights, the quasar was in an optical faint state displaying fluctuations on a small-scale. When observed during three nights, it became more variable and brighter. In its active state, PKS 0736+017 showed a rapid flare followed by quasi-periodic low-amplitude variations.

StunRay is a less-lethal optical incapacitation effector developed by Genesis Illumination Inc. It uses collimated incoherent (non-laser) broad spectrum visible and near infrared light from a short-arc lamp to safely and temporarily impair vision, disorient and incapacitate aggressors for 5 seconds to 3 minutes without causing physical harm.
However telephoto designs increase the number of lens elements and can introduce flare and exacerbate some optical aberrations. Catadioptric lens - catadioptric lenses are a form of telephoto lens but with a light path that doubles back on itself and with an objective that is a mirror combined with some form of aberration correcting lens (a ...
Coma of a single lens. Each cone of light focuses on different planes along the optical axis. In optics (especially telescopes), the coma (/ ˈ k oʊ m ə /), or comatic aberration, in an optical system refers to aberration inherent to certain optical designs or due to imperfection in the lens or other components that results in off-axis point sources such as stars appearing distorted ...
