Spectral sensitivity characteristics:
The.following.diagram.shows.that.the.photodiode.with.fil-
ters.fulfils.the.requirements.of.the.CIE.(International.Com-
mission.on.Illumination),.with.regard.to.spectral.sensitivity.
and.the.photopia.curve.V.(

) .
The. spectral. sensitivity. function. indicates. how. large. the.
number. of. irradiated. photons. must. be. (per. cm². and. se-
cond).at.each.wavelength,.so.that.the.light.is.just.detected ..
The.electric.current.is.set.in.relation.to.the.irradiated.light.
power ..A.value.of.0 .8.or.80%.means.that.20%.of.the.in-
cident.photons.are.lost,.i .e ..make.no.contribution ..Losses.
