مرشح أشعة فوق البنفسجية (بالإنجليزية : UV filter) هو مرشح قد يتكون من عدسة واحدة أو عدة عدساتلامتصاص ومنع نفاذ الأشعة فوق البنفسجية. وتستعمل مرشحات الأشعة فوق البنفسجية في الكاميرات بغرض منع الزغللة والغيام التي تنشأ عن ضوء الأشعة فوق البنفسجية في الصور. (ar) UV-Filter (eigentlich UV-Sperrfilter) sind in der Fotografie spezielle Filter, die ultraviolettes Licht blockieren. Sie sehen farblos oder ganz schwach gelblich eingefärbt aus. (de) Un filtre ultraviolet ou filtre UV est un composé chimique qui bloque ou absorbe les radiations ultraviolettes. Les filtres UV sont utilisés notamment en cosmétique dans les crèmes solaires pour protéger la peau contre les effets nocifs de ces radiations et en photographie, dans certains plastiques (pour les rendre résistants aux UV solaires) ou encore en optique pour protéger les systèmes optiques ou les détecteurs de ces rayonnements. Il existe deux types de filtres ultraviolets : organique et minéraux. (fr) Los filtros UV se usan en fotografía general para reducir brumado y neblina creadas por la luz ultravioleta. Un filtro UV es a la luz visible, y debe colocarse antes de la lente. Como los filtros UV son usualmente baratos (unos 10 euros o 20 US$, aunque depende del tamaño), muchos los usan para proteger las lentes. Y a veces son preferibles, frente a otras clases de filtros más intrusivos, tales como el filtro de densidad neutra. El filtro UV absorbe la radiación ultravioleta sin cambiar la exposición. Como con muchas imágenes, muchos no ven diferencia cuando se usa un filtro UV. * Datos: Q1118402 (es) Filter ultraviolet adalah bahan senyawa individu atau campuran yang berguna untuk mencegah agar cahaya ultraviolet (UV) tidak melaluinya. Filter UV digunakan dalam tabir surya untuk melindungi kulit atau dalam fotografi untuk mengurangi tingkat cahaya ultraviolet yang merekam media perekam. (in) UV filters are compounds, mixtures, or materials that block or absorb ultraviolet (UV) light. One of the major applications of UV filters is their use as sunscreens to protect skin from sunburn and other sun/UV related damage. After the invention of digital cameras changed the field of photography, UV filters have been used to coat glass discs fitted to camera lenses to protect hardware that is sensitive to UV light.

what does "spanning" the color spectrum mean? Are they UV filters if they act on the visible spectrum? (en) |
