Dichroic glass is glass which can display multiple different colors depending on lighting conditions. One dichroic material is a modern composite non-translucent glass that is produced by stacking layers of metal oxides which give the glass shifting colors depending on the angle of view, causing an array of colors to be displayed as an example of thin-film optics. The resulting glass is used for decorative purposes such as stained glass, jewelry and other forms of glass art. The commercial title of "dichroic" can also display three or more colors (trichroic or pleochroic) and even iridescence in some cases. The term dichroic is used more precisely when labelling interference filters for laboratory use.

- ダイクロガラス(英語：Dichroic glass)とはガラスの一種。 (ja)
- Szkło dichroiczne jest to szkło, na które w próżni, za pomocą działa elektronowego, nałożono tlenki metali (złota, srebra, tytanu, chromu, aluminium, cyrkonu, magnezu i krzemu) w postaci wielu cienkich warstw. Warstwy te mają grubość łącznie około 700 nm. Termin dichroiczne oznacza grę dwóch kolorów, tzn. szkło takie, przepuszczając dany kolor, odbija jego barwę dopełniającą. Dzięki nałożeniu 30-50 warstw widziany kolor jest różny w zależności od kąta patrzenia i padania światła. To, co widzimy, to interferencja światła odbitego od tych warstw, które same w sobie nie mają koloru. Efekt ten nosi nazwę iryzacji. (pl)

| - Dichroitisches Glas, auch unter dem Namen Farbeffektglas bekannt, verändert durch Beleuchtung, Sonne, Wolken oder durch den Betrachtungswinkel seine Farbe. Als dichroitisch (von griech. „dichroos“ = zweifarbig) werden Filter bezeichnet, die bestimmte Wellenbereiche durchlassen und die anderen reflektieren. Dies hat zur Folge, dass je nach Sichtwinkel eine andere Farbe erscheint, das Licht aber nicht absorbiert und in Wärme umgewandelt wird. Das dichroitische Glas besteht aus mehreren optischen Interferenzschichten. Durch die Kombination hoch- und niedrigbrechender Schichten entsteht ein Regenbogeneffekt. Die Farben, die durch einen dichroitischen Filter sichtbar gemacht werden, umfassen fast das gesamte Farbenspektrum – sowohl die additiven (Rot, Grün, Blau) als auch die subtraktiven (Gelb, Magenta, Cyan) Farben.

- Dichroic glass is glass which can display multiple different colors depending on lighting conditions. One dichroic material is a modern composite non-translucent glass that is produced by stacking layers of metal oxides which give the glass shifting colors depending on the angle of view, causing an array of colors to be displayed as an example of thin-film optics. The resulting glass is used for decorative purposes such as stained glass, jewelry and other forms of glass art. The commercial title of "dichroic" can also display three or more colors (trichroic or pleochroic) and even iridescence in some cases. The term dichroic is used more precisely when labelling interference filters for laboratory use. Another dichroic glass material first appeared in a few pieces of Roman glass from the 4th century and consists of a translucent glass containing colloidal gold and silver particles dispersed in the glass matrix in certain proportions so that the glass has the property of displaying a particular transmitted color and a completely different reflected color, as certain wavelengths of light either pass through or are reflected. In ancient dichroic glass, as seen in the most famous piece, the 4th-century Lycurgus cup in the British Museum, the glass has a green color when lit from in front in reflected light, and another, purple-ish red, when lit from inside or behind the cup so that the light passes through the glass. This is not due to alternating thin metal films but colloidal silver and gold particles dispersed throughout the glass, in an effect similar to that seen in gold ruby glass, though that has only one color whatever the lighting.

- Il vetro dicroico è un vetro contenente micro-strati di ossidi metallici che danno al vetro così trattato proprietà ottiche particolari e un aspetto cangiante, sfruttato a scopi artistici e di alta tecnologia (si pensi alle lampade alogene "dicroiche" usate per illuminazioni particolari come in microscopia a luce trasmessa). L'invenzione del vetro dicroico è spesso erroneamente attribuita alla NASA (filtri dicroici), ma il vetro dicroico risale almeno al IV secolo, come si vede dalla Coppa di Licurgo. La moderna produzione di vetro dicroico o bicolore si ottiene attraverso un processo di rivestimento multistrato. Cristalli di quarzo e ossidi di diversi metalli come titanio, cromo, alluminio, zirconio, magnesio sono vaporizzati con un raggio elettronico in una camera a vuoto, dove finiscono per condensarsi su una superficie in forma cristallina. Questo materiale è poi generalmente lavorato a caldo, e può essere utilizzato in forma grezza. La principale caratteristica del vetro dicroico è il colore della luce riflessa che è cangiante, questo perché il colore della luce trasmessa è differente da quello ottenuto per riflessione. L'industria romana del IV secolo raggiunse un uso così sofisticato di additivi che portò alla produzione di vetri dicroici. (it)
