Extreme ultraviolet (EUV) photodetector is low-noise

OPTO DIODE SXUV20C low-noise, extreme ultraviolet (EUV) photodetector provides a large 20mm² circular active area that provides a substantial surface for easy alignment to the EUV laser. Device boosts responsivity in the 1nm to 200nm wavelength region and is stable over long periods of time when exposed to high intensity EUV energy. Device boosts hardness in extreme UV environments while providing lower noise than firm’s previously released products. http://www.optodiode.com
