Hamamatsu Corp. has introduced a hemispherical acrylic lens designed to increase anode sensitivity and relative output in the company's 11/8-in. photomultiplier tubes. Attaching the lens to the entrance window of side-on PMTs widens the capture area by a factor of 3, increasing the amount of incident light reaching the photocathodes. Improvement in X and Y axes occurs at wavelengths above 300 nm.
