WebDec 9, 2024 · What Does Photodegradation Mean? Photodegradation is the change, typically undesirable, in the properties of a material. Quite literally, it means the degradation of a material due to photon exposure. Photo degradation is a major concern with some polymers and other materials, where ultraviolet (UV) light causes the polymer to oxidize, thus ...

WebMar 23, 2024 · Photon starvation is one source of streak artifact which may occur in CT. It is seen in high attenuation areas, particularly behind metal implants. Because of high attenuation, insufficient photons reach the detector. During the reconstruction process, the noise is greatly magnified in these areas leading to characteristic streaks in the image 3. WebThe photo active compound of AZ ... UV-hardening further enhances the softening point. Beyond this temperature, the developed resist structures start rounding. From 120°C on, photoresists more and more react with oxygen from air (brownish coloring, embrittlement) promoting the formation of cracks. However, dependant from subsequent pro-

A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.
