melanoscope|ˈmɛlənəʊskəʊp|
[ad. G. melanoskop: see melano- and -scope.]
A combination of coloured glasses, devised by Lommel in 1871 (Pogg. Ann. CXLIII. 489) for exhibiting certain optical properties of chlorophyll; by intercepting nearly all except the middle red rays of the spectrum, it causes green plants seen through it to appear almost black.
