RE: Laser Safety Calculations

Hi Rich,

Sounds reasonable.  Actually, it sounds like a tool that a transciever
vendor would offer on a webpage to assist their customers in development
using that vendors' component...  Has anyone come across such a thing ?

Regards,
George

Hi George and Chris:


Better still, TC76 should provide a spreadsheet such
that, upon entering all the data, the spreadsheet does
the calculations and gives you the emission level and
the emission Class.


Regards,
Rich

Chris,

Try contacting Donald Drozdenko at HP (Aligent) at 408-435-5807.  Don headed
the testing / certification efforts for HP's Laser  Led products back when
825 first emerged.  Another person who may be able to help is Dr. Joseph
Tajnai (408)435-6331, also from HP and member of TC76.

Good Luck,
George

All,

I too share the sentiments of another member of the group that the
calculations for laser safety in EN 60825-1 are made somewhat more difficult
to follow due to the difficulty of reading the diagrams and the symbols.  I
myself have looked at the diagrams a few times and can't figure out what
symbol is representing what angle ...

I would love to see a few examples and more complete descriptions of the
nomenclature.
Is there a text out there, either commercial or from IEC that goes through
these calculations in more detail?  

Thanks in advance
