lens
原文
a clear disk that focuses light, as in a camera or microscope. in the eye, the lens is a clear, curved structure at the front of the eye behind the pupil. it focuses light rays that enter the eye through the pupil, making an image on the retina (light-sensitive layers of nerve tissue at the back of the eye).
日本語訳
光を収束させることのできる透明な円盤のことで、カメラや顕微鏡に使用されている。眼では、眼の前部の瞳孔の後方に位置する透明で彎曲した構造体である水晶体が、レンズの役割を果たしている。瞳孔から眼の内部に入ってきた光がこのレンズによって収束されることにより、網膜(眼の後方に存在する、光を感知できる神経組織の層)上に像が作られる。

語源
Borrowed from Latin lēns (“lentil”); Medieval Latin later taking on the sense of "lens"; a semantic loan from Arabic عَدْسَة (ʕadsa, “lentil; optic lens”).
名詞
lens (plural lenses or (廃れた用法) lens or (まれに) lentes)
- An object, usually made of glass, that focuses or defocuses the light that passes through it.
- 2013 July-August, Catherine Clabby, “Focus on Everything”, in American Scientist:
- Not long ago, it was difficult to produce photographs of tiny creatures with every part in focus. That’s because the lenses that are excellent at magnifying tiny subjects produce a narrow depth of field.
- A device which focuses or defocuses electron beams.
- (geometry) A convex shape bounded by two circular arcs, joined at their endpoints, the corresponding concave shape being a lune.
- (biology) A genus of the legume family; its bean.
- (anatomy) The transparent crystalline structure in the eye.
- 2013 July-August, Fenella Saunders, “Tiny Lenses See the Big Picture”, in American Scientist:
- (earth science) A body of rock, ice, or water shaped like a convex lens.
- (programming) A construct used in statically-typed functional programming languages to access nested data structures.
- (by extension, figurative) A way of looking, literally or figuratively, at something.

Latin
語源 1
Unknown, likely a borrowing from an unidentified source.
Compare Old High German linsa, Lithuanian lęšis, Old Church Slavonic лѧща (lęšta), and Albanian lend (Proto-Albanian *lenta), sounding too similar for a coincidence, however different enough to prohibit reconstruction of a common PIE protoform. May also be related to Ancient Greek λάθυρος (láthuros).
If ultimately a non-IE substrate loanword, locating the source is virtually impossible because cultivation of lentil was widespread in the region since the Neolithic.
発音
- (Classical) IPA(key): /lens/, [ɫ̪ẽːs̠]
- (modern Italianate Ecclesiastical) IPA(key): /lens/, [lɛns]

語源 2
Unknown. According to de Vaan, perhaps a deformed form of what is found as Proto-Slavic *gňìda (“nit”), Proto-Germanic *hnits (“nit”), Ancient Greek κονίς (konís) (gen. κονίδος (konídos)), Armenian անիծ (anic, “nit”); he proposes Proto-Indo-European *dḱ(o)nid- > *dkni-n-d- > *dklind- > Proto-Italic *(d)lind-. However, like the Indo-European cognates, it may be of substrate origin.
