Hey thanks so much for the info. +rep!!

and WOW that pen host is sexy. Buying one now.

A 532nm Module comes complete with the 808nm pump LD
and the crystals already aligned to produce 532nm and the
Module already includes a lens that 99% of the time is adjustable.

A pen host is a tube to put the batteries and the 532nm Module.

On a Forum it is important to clearly explain what it is you are
trying to say...

Remember.... you are trying to put an image that you see in your
mind into the mind of others by the use of words on a computer
screen...

(Garbage in.... Garbage out)...
