Here's the summary and some own experimental data.
First off all thank you all for your replies.

the mirrors of your base (Isolde Le Trong)

We have both LED and cold light sources attached to our Zeiss Stemi

not using LED lights however the solution from Zeiss is very good

We have tested the Zeiss LED plate with hanging and sitting drop trays
and found it it unsuitable for looking at crystals. The reason is the
really low contrast with this kind of diffuse illumination. Obviously,
contrast is generated by refraction at crystal/mother liquor

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?

Hi there,
*warning, reading beyond this line might expose you to non CCP4
related topics*
anybody out there who could do the following experiment:
Turn on your microscope and measure the temperature after 30 minutes
where you would place your precious crystal tray.
In particular I'm intere
