Dear colleagues,

At the moment we are in dire need of quartz windows. We have ordered them from a supplier, but it will take a long time for them to arrive. Therefore, we would greatly appreciate it if you could lend us some quartz windows in order to continue with our work. The quartz windows can be either round or square. Ideally, they should be larger than one inch, either in diameter or in length, depending on the shape of the window. A semiconductor film will be deposited onto the quartz. Subsequently, a spectroscopic characterization of the film will ensue. The substrates will not be damaged in any way. Thanks for reading this message.
