ATM Light Source Help

["Alfredo Neves" <aneves@adsl.tie.cl>]

Hi,

I am trying to build a tester for the waineo null test and I am having
problems injecting sufficient light into a 50 micron fiber. Basicaly I
am using a white led and gluing the fiber to the led. There is just
sufficient light for seen some dim ronchi lines. What I would like is
some for of getting ALOT of light so I can see fine surface details. Is
anyone using a real high light power set up.

Regards,

Alfredo

P.S. Yes I have checked that end of my fibers are correctly cut and
polished!
