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” . Typical applications of High Speed Free-space photo detectors include: Pulse Form Measurements Pulse Duration Measurements Precise Synchronization Mode Beating Monitoring Heterodyne Measurements Relative spectral sensitivity of 11HSP-FS1 Relative spectral sensitivity of 11HSP-FS2 Model 11HSP-FS1 11HSP-FS2 Wavelength range, nm 400-1100 400-1100 Rise time, ns <1 <10 Spectral Sensitivity (λ=850 nm) 0.62 A/W 0.62 A/W Pulse width (FWHM), ns 1 10 NEP, (W/√ Hz) 2.9×10-14 4×10-14 Capacitance VR=5OV, pF 2.2 20 Material Si Si Dark current, nA 1 10 Sensitive area, mm2 1 7.5
