Request InfoHamamatsu CorporationHamamatsu Corp.'s R5509-42 is a photomultiplier tube (PMT) that detects extremely low light levels at wavelengths up to 1400 nm. According to the company, this development allows a PMT to perform photon counting in the infrared for the first time, making new biomedical and scientific applications possible. The R5509-42 has a quantum efficiency of 0.1% at 1300 nm, cathode radiant sensitivity of 5 mA/W and anode radiant sensitivity of at least 1000 A/W. Rise time is typically 3 ns at 1500 VDC, amplification is typically 1 3 106 and anode dark current at 1500 VDC is typically 5 nA.See full productRelated content from Photonics MediaWEBINARSPhotonics.com 1/12/2023A Proven, Portable, and PIC-Based Methodology for Cultivating a Next-Generation WorkforceWith the passage of the CHIPS and Science Act and growing demand for photonic integrated circuit technology, the semiconductor industry is once again gaining momentum.
