The X-ray Multi-Mirror is an advanced optical system designed to focus X-ray radiation from astronomical sources. It uses multiple mirrors arranged in a specific geometry to capture and redirect X-rays, which are typically difficult to focus due to their high energy. This technology allows scientists to observe celestial objects like black holes and neutron stars with greater clarity. These mirrors are often made from materials like beryllium or glass and are coated with reflective layers to enhance their efficiency. The X-ray Multi-Mirror system is crucial for space telescopes, such as the Chandra X-ray Observatory, enabling detailed studies of the universe's most energetic phenomena.
