fotohromatski filtar sunčeve blještave svetlosti

filter that reversibly alters its luminous
transmittance factor under the influence of sunlight

NOTE This alteration is not instantaneous, but is a
function of a temperature and material dependent time
constant. In this way, the luminous transmittance factor
of the filter adjusts itself within certain limits to the
ambient radiant flux.

filtar kod koga se reverzibilno menja koeficijent transmisije svetlosti pod uticajem sunčeve svetlosti

NAPOMENA Ova promena nije trenutna, već je vremenska konstanta koja zavisi od temperature i materijala.
