Re: green line on I-90K

Hi James

The correct part nos are:

High reflector 0903-004-00
Output coupler 0161-453-00

The 'Argon' green output coupler 0161-446-00 also works fine (it has the
same 5m curvature)

Output couplers always have a notch cut out of the side which seats them in
the output coupler holder. High reflectors never do.

On a I90K-4W I get around 250mW MLBG. Although I would check you have the
magnet set to low. I could only get 10mW on high. On single line mode you
get 3 lines (2 blue and 1 green) all of which give at least 60mW which is
adequate for most MoFlo applications.

Cordially,
