Lensa

Lensa utawa uga diarani Kanta yaiku sawijining srana kang awujud kaca bening gepeng sing duwe sisi-sisi kang simetris. Lensa duwe kagunan kanggo ngumpulake cahya marang siji titik utawa malah nyebarake cahya kang liwat ing tengahe. Lensa sepisanan dipangerteni saka catatan sandiwara Yunani Kuno liwat cathetane Aristhophane The Clouds (424 SM) kang nyebutake anane istilah gelas-gelas pembakar (lensa cembung kang digunakake kanggo mokusake sinaring srengenge kanggo nyiptakake geni) ing karyane. Wong kang nemokake teori babagan lensa sepisanan tur uga mratelakake kadadean bayangan ana ing retina yaiku nsawijining fisikawan muslim saka Arab kang asmane Alhazen (Abu Ali al-Hasan Ibn Al-Haitham)
