Optical Receiver, AC coupled, 800-1750 nm Biased InGaAs Detector, 1.5 GHz
Model: 818-BB-30A
Product Series Overview
1.2 to 1.5 GHz Optical ReceiversThe 818-BB-30A InGaAs Optical Receiver consists of a free-space biased InGaAs photodetector with a 0.10 mm active diameter and a 400 ps rise time. It has a built-in amplifier with approximately 26 dB of gain. It is excellent for viewing rapid modulation of low-power CW lasers or other light sources in the μW regime. The detector is AC coupled and features a bandwidth of up to 1.5 GHz. A wall plug-in style power supply is provided with this unit. 818-BB Series Biased Photodiode Detectors are cost effective diagnostic tools suitable for a variety of high speed applications such as viewing of Q-switched, mode-locked, or rapidly modulated laser signals and picosecond laser alignment. It is equivalent to Coherent's Model ET-3000A (P/N 120-10036-0001).
NOTE-These detectors are very susceptible to damage by electrostatic discharge (ESD). Please use ESD protective measures, like the FK-STRAP, when unpacking and handling these devices.
Silicon Optical Receiver
The 818-BB-21A features a 0.4 mm diameter silicon photodetector with a wavelength range of 320 to 1000 nm. This 24 V biased free space receiver has an acceptance angle of 10°. The Amplified PIN Photodetector utilizes the photovoltaic effect to convert optical power into an electrical current.
InGaAs Optical Receiver
The 818-BB-30A features a 0.1 mm diameter InGaAs photodetector with a wavelength range of 800 to 1750 nm. This 24 V biased free space receiver has an acceptance angle of 20°. The Amplified PIN Photodetector utilizes the photovoltaic effect to convert optical power into an electrical current.
Measure Pulsewidth or Frequency Response
These high speed detectors make a great free space front end for an scope or spectrum analyzer. When terminated into 50Ω into an oscilloscope, the pulsewidth of a laser can be measured. When terminated into a spectrum analyzer, the frequency response of a laser can be measured.
Optical Post Mounting
An 8-32 threaded hole at the bottom of 818-BB biased photoreceivers allows for optical post mounting.
Handle With ESD Care
These detectors are very susceptible to damage by electrostatic discharge (ESD). Please use ESD protective measures, like the FK-STRAP , when unpacking and handling these devices.
