Web1 Oct 2002 · This chain lengthening effect of stray light would not be preventable when synthesis involves a directly photosensitive 5′‐blocking group. If the 5′‐blocking group is acid labile and released with photogenerated acid, the presence of low concentrations of weak base will prevent the effect of stray light. WebIt is imperative that optical system designers understand its consequences on system performance and adapt the design process to control it. This book addresses stray light terminology, radiometry, and the physics of stray light mechanisms, such as surface roughness scatter and ghost reflections.
