Meets Single Fault Failure Requirements:
Electrotechnical Commission) 60825-1 is applicable to safety of laser products emitting laser radiation
in the wavelength range 180 nm to 1 mm.
IEC 60825-1, EN 60825-1, and JQA require the laser products to meet
Single Fault Failure Requirements, which require the highest
emitted power under reasonably foreseeable single fault failure
conditions never higher than the laser classification.
Therefore, for class II or class 2 laser products, the output power is
<1mW, the highest emitted power under reasonably
foreseeable single fault failure conditions for this laser shall never be
Obviously, the driver PCB for diode lasers is of importance, in the case of
a flaw or defect, it may cause the laser product to emit above
the AEL (accessible emission limit) of the desired Class. Our PS series
laser diode modules with the thought of safety would eliminate this risk
and keep the laser in the safe range as required.
The following PS-series class II laser diode modules are designed with the driver PCB
to meet Single Fault Failure Requirements for
IEC 60825-1, EN 60825-1, and JQA.
