Dear Colleagues:
I have a few units of the photo-therapy units manufactured by Burton and sells under the following brands:
AIR SHIELDS, HILL-ROM, DRAGER, OHMEDA model PT1400 , specifically I have all OHMEDA, but the units are the same.
Someone who doesn't knows anything about optics move the lenses and then all units doesn't works with homogeneous light field.
I need to put this optics in the focal point to obtain the better performance in light field.
Any one have the service manual or maybe knows the correct distances between the lenses and the lamp?
any help will very, very usefully
Thanks in advance
best regards
Jorge
