Development of a UV-transparent Lens Array for Enlarging the Effective Area of Multichannel SiPMs
Akira Okumura, Akira Asano, Kazuhiro Furuta +4
We developed a UV-transparent lens array that can increase the photon detection efficiency of a silicon photomultiplier (SiPM) array comprising of 64 pixels ( mm each…
