Optoelectronic Unit

MINI-PAM-II/B (Blue Version)
Measuring light: Blue (470 nm) LED, standard modulation fre-
quencies 5 to 25 Hz, adjustable in increments of 5 Hz, and 100
Hz, measuring light PAR at standard settings = 0.05 µmol m

. Fluorescence at wavelengths greater than 630 nm is measured
Actinic light: Same blue LED as for measuring light, maximum
actinic PAR = 3000 µmol m
pulses = 6000 µmol m

MINI-PAM-II/R (Red Version)
Measuring light: Red (655 nm) LED, modulation frequencies
and PAR as described for MINI-PAM-II/B. Fluorescence at wave-
lengths greater than 700 nm is measured
Actinic light: Same red LED as for measuring light, maximum
PAR of actinic light and saturation pulses as described for MINI-
