Bake out

We use the temperature monitoring design, made by E. Wodey, for the out of loop measurements during the out baking.

Talk by E. Wodey for the explanation of the monitoring system:2016-08_geoq_ctp_ew.pdf

What is the maximum temperature gradient that can be applied (continuously) between the two faces of the 1/2“ 3mm BK7 and fused silica windows? Response from Jeremy at Thorlabs: The maximum temperature will be around 200°C or so. We do not spec a maximum temperature gradient since it can depend on the thermal boundary conditions and geometrical boundary conditions of the window. However, I would recommend UVFS over N-BK7 because of its much lower coefficient of thermal coefficient.
