Fiber-Optic Receivers

These New Focus high speed fiber-optic receivers offer bandwidths up to 38 Ghz for receiving fiber optic data while delivering the lowest noise and cleanest responses possible.
These 12 GHz fiber-optic receivers are ideal for applications that require high sensitivity, high speed, and clean responses. The high gain and gradual, well-behaved roll-off of the frequency response also make them useful for frequency-domain measurements.
 - Visible and NIR versions
 - Switchable DC-coupled or AC-coupled output versions
 - Singlemode and Multimode fiber connector options
 - Ultra-clean pulse response
 - Ideal for characterizing OC-192 and 10-GbE components

Free Space Optical Receivers

These New Focus optical receivers have bandwidths in the kHz to MHz range for detecting high speed free space optical signals with the lowest noise and cleanest responses possible.
Our large area optical receivers operate from the UV to the IR spectrum for laser or signal detection from 190 to 1750 nm. The large photodetectors used in these designs make alignment easy. You can tweak your experiment without worrying about the beam wandering off the photodetector. Just position the photodetector close to where you think the laser beam is and you’ll see a signal. No more time-consuming and tedious photoreciever alignment procedures.
 - Large photodetector diameter for easy alignment
 - Adjustable gain settings
 - Compact housing for tight spaces

Balanced Optical Receivers

For noise sensitive experiments, we offer balanced photoreceivers that suppress up to 50 dB of laser / source intensity noise in experimental set-ups. These balanced optical receivers with two well-matched photodetectors can eliminate the need for lock-in amplifiers and can make all of the difference when you are trying to detect a small signal in applications like absorption spectroscopy, or heterodyne detection.
