Jurgen,
From your question I assume that you are having problems with the
warming up of the crystal tray due to the microscope light.
Did you consider the use of an external cold light source like the
KL1500 LCD?
I do not feel anything warming up.
Which microscope are you using?
The LED systems I have tried are not bright enough.
Try them before you buy.
Suggestion - request a demo to your supplier.
Cheers,
Joao
