The H14447 is a photomultiplier tube module with a 28 mm diameter head-on photomultiplier tube and an integrated high-voltage power supply, designed for high-speed light detection. It features a 25 mm effective area, a rise time of 350 ps, and a spectral response from 300 to 650 nm with peak sensitivity at 420 nm. The module operates from a +4.8 to +5.5 V input, provides a current output, and accepts a control voltage of +1.6 to +2.0 V with 1 MΩ input impedance. It includes a +2.5 V reference output and is housed in a 105 g package measuring 35.0 mm in diameter and 105 mm in length. The operating ambient temperature ranges from +5 to +50 °C.
The H14447 is a photomultiplier tube module containing a high-speed response 28 mm diameter head-on photomultiplier tube and a high-voltage power supply circuit. Besides high-speed response, these modules feature high gain and have a large effective diameter for better light collection making them ideal for high-speed underwater optical communications.
