WebJul 1, 2005 · This is very different from cylindrical lens where the central tube gives the strongest beam intensity. With increasing distance from the lens exit, X-ray beams start to be focused. This is similar to situation with the cylindrical lens. However, extent of “focusing” by the parallel beam lens is much weaker than that of the cylindrical lens. Weblength tuning-based 1D beam steering based on the on-chip OPAs and 3D printed curved cylindrical lenses on 3-lm silicon-on-insulator (SOI) platform. The output from the OPA chips has higher beam divergence in vertical direction; thus, there is a need for off-chip curved cylindrical lenses to collimate vertically the beam. security alarm for shop
