Detectors For EUV Monitoring Satellites

Extreme Ultraviolet (EUV) light, with wavelengths between 10 and 120 nanometers, plays a crucial role in space weather monitoring, climate research, and astrophysics. Accurate EUV measurement enables scientists to study solar flares, coronal mass ejections (CMEs), and their impact on satellite communications, GPS, and geomagnetic storms.

Opto Diode’s space-qualified EUV photodiodes are designed for long-term reliability, maintaining accurate signal detection throughout a mission’s lifetime, even in harsh radiation environments. These detectors provide precise measurements across a wide range of wavelengths with minimal signal degradation, ensuring consistent performance in space applications. For specialized wavelength detection, bandpass filters can be directly deposited onto the photodiode’s sensing area or implemented through external EUV-specific filters.

With a strong history of innovation, Opto Diode offers both standard and custom EUV photodiodes tailored for space applications. Their detectors contribute to missions such as those led by the European Space Agency (ESA), enhancing our understanding of solar activity and improving satellite resilience to solar radiation.

Key products include models like the AXUV100TF series, featuring directly deposited thin-film filters for selective EUV wavelength detection, and SXUV high-speed photodetectors, optimized for rapid EUV signal response. These technologies ensure superior performance for space weather monitoring, astrophysics, and climate research, reinforcing Opto Diode’s commitment to advancing global communication and space exploration.
