The 11HSP-FSx is a family of high speed optical signal detectors. These photodetectors are well suited for measuring optical pulses with durations of a few ns or longer and also for pulse shape monitoring. The 11HSP-FS1 can also be used for intensity noise measurements of CW lasers in the range of 10 Hz - 300 MHz, while the 11HSP-FS2 has a large sensitive area. Photodetectors can be integrated into a scheme for generating triggering pulses. Recommended external bias voltage is 24-42V. Our recommended power supply: Model: GE12I24-P1J 24 V; 0.625 A Dimensions: 70.7x40x38.8mm weight: 97g connector "2.1/5.5" .
