Is there anyway of preventing this? The diode would have to be cooled before it is turned on. I guess I am wondering how long can it be cooled before it starts to condensate, given normal room temperature and humidity.

you pot the connections and on the high end stuff, you seal everything up tight and put it under a inert gas so there's no water in the air inside. All of my stuff gets bottled in argon when it goes deep. It's often close to freezing, so florida air + freezing in seawater = condesationa all over inside. can't have that. [/quote]
If you're good with electronics, you could also rig up from scratch a digital thermostat to control the temp of the TEC to let say 10C, similar to what they do in high powered DPSS lab modules (or whatever temperature that would prevent condensation from occurring). If you're not so good, you could also try and make one from a ready made thermostat unit that you can easily buy from your local electronic shops and pair the output / alarm with a 555 timer IC to control the TEC via a switching relay and you're done. Easy isn't it ;D.
