The science driving the design of modern X-ray observatories always poses a large challenge to the X-ray observatory designers. The requirements for a large effective area, high spatial resolution, and a large field of view affect the optical design of the X-ray optics. In my talk, I will discuss the different X-ray optics technologies used in modern X-ray observatories. To make such optics, adequate X-ray test facilities are needed to support their development, testing, and calibration. An overview of the different X-ray test facilities available worldwide for testing and calibrating these optics will be presented. A detailed description of the PANTER X-ray test facility of the Max-Planck-Institute for Extraterrestrial Physics and the work that has been and is being done for current and planned X-ray observatories such as eROSITA, Einstein Probe, SVOM, and ATHENA. Also, work supporting the eXTP and NASA AXIS probe mission will be presented.
