▎ 摘　　要

NOVELTY - The window has the thin membranes made of carbon or carbon-based materials, including graphene, diamond, diamond-like carbon (DLC), pyrolytic carbon or graphite, which are known to be highly transparent to certain radiation or particles. The thin carbon-based membranes with typical thicknesses ranging from 50 nm to 2000 nm are used as X-ray windows for X-ray detectors including silicon drift detectors (SDD), PIN diodes, silicon detectors, cadmium telluride (CdTe)-detectors and proportional counters, or X-ray sources consisting of the radioactive iron isotope. (Incomplete specification, abstract based on available information published by the patent office). USE - Carbon based window for filtering infrared radiation in combination with detecting X-ray photons. ADVANTAGE - The infrared radiation is avoided from hitting the sensitive detector volume. The membrane is separately placed in front of the detector that absorbs near infrared radiation with high efficiency and is nevertheless transparent for X-ray photons. The silicon detectors detect infrared radiation with wavelengths below 1400 nm with very high efficiency.
