The JUNIOR-PAM fluorometer is a miniaturized instrument capable of carrying out the full range of saturation pulse analysis of photosystem II. A small box of 11.5 x 6.5 x 3.0 cm contains all optical and electronic components. The fluorometer is connected to the sample via a 50 cm long single plastic fiber with 1.5 mm diameter.

The JUNIOR-PAM employs either a blue power LED (Version JUNIOR-PAM) or a white power LED (Version JUNIOR-PAM/W) for pulse modulated excitation light, actinic illumination, and saturating pulses. The fluorometer has a far-red LED for selective excitation of PS I, which is needed for the determination of F0’ level fluorescence.

Two different types of leaf-clips are provided. Measurements in ambient light are performed with a 60° leaf clip. A magnetic leaf clip is provided for dark-acclimation followed by measuring the maximum photochemical yield of photosystem II (FV/FM).
