Laser Classification
QS18AF Models: N/A
QS18LAF Models: Class 1 laser product; Complies
with IEC 60825-1:2001 and 21 CFR 1040.10, except
for deviations pursuant to Laser Notice 50, dated
7-26-01
QS18LAF250 Models: Class 2 laser product; Com-
plies with IEC 60825-1:2001 and 21 CFR 1040.10, ex-
cept for deviations pursuant to Laser Notice 50, dated

Application Notes
NPN off-state leakage current is < 200 µA for load re-
sistances > 3 kΩ or optically isolated loads. For load
current of 100 mA, leakage is < 1% of load current.
