Stray light is light in an optical system, which was not intended in the design. The light may be from the intended source, but follow paths other than intended, or it may be from a source other than the intended source. This light will often set a working limit on the dynamic range of the system; it limits the signal-to-noise ratio or contrast ratio, by limiting how dark the system can be. Ocular straylight is stray light in the human eye.

  • Il termine inglese straylight o stray light (letteralmente "luce sporadica") indica un tipo di rumore strumentale nei sistemi ottici dovuto a luce non voluta. Negli spettroscopi le principali fonti di straylight sono le imperfezioni dei monocromatori e i fenomeni di diffusione che avvengono all'interno dello strumento, ma anche gli stessi rilevatori generano rumore.

  • 미광은 반사망원경에서, 설계에 오차가 생기거나 거울의 반사각도, 곡률 등에 문제가 생겨 관측되는 이상한 빛을 정의한다. 이는 관측에 오차를 주며, 때로는 관측에 심각한 문제를 주기도 한다. 또한 고치기도 힘들어서 미광이 심한 망원경은 버려야 하는 경우가 다수다. (ko)
