Good-day,
In my research, I will be photographing droplets resting on horizontal surfaces inside a steel well in a furnace running at 750C, though I may later wish to raise the temperature by a few hundred degrees celsius.
To permit imaging, I require an approximately 10-13 cm diameter by 2-5 mm thick window in the side of the well (open-topped, stainless steel, cylinder, 15 cm diameter, 6.5 cm thick walls) that can withstand these temperatures, while remaining hermetically sealed (during later experiments, we will be sealing the top of the well and running a chlorine atmosphere).
As the well is a cylinder, the simple flat, bolt-on type windows I have seen in appropriate sizes do not seem as though they could be modified to work, and most do not meet my temperature requirements.
I was thinking if it would be possible to buy a window (i.e., quartz) hermetically sealed to a ring of metal which I could then weld or screw onto a (threaded) fixture previously welded to the well wall (i.e., a cylindrical tube open at both ends, with one end welded to the well and the other to be attached to the window assembly). If the threaded design were pursued, I would also require an appropriate sealant.
I am interested as to possible window designs or any suggestions or information (i.e., relevant companies, etc.) that would be suitable, as well as being low cost (i.e, < CAN$500 (~US$380), excluding labour).
Thank you for your time.
Auf wiedersehen,
James
