Newport / New Focus 2011-FC 200-kHz Front-End Photoreceiver

Newport / New Focus 2011-FC 200-kHz Front-End Photoreceiver

This New Focus 2011-FC 200-kHz Front-End Photoreceiver is used, and in excellent condition. These units have been modified to run from a bench-top power supply instead of 9V batteries. No issues with dead or dying batteries with these units. There is a New Focus microconnector on the battery housing. They can be hooked into a New Focus 0901 +/- 15-V Power Supply with a 0922 accessory cable. Alternatively, it can be hooked into a standard +/- 15V lab power supply with the New Focus 0921 microconnector-to-bannana jack cable. Browse or search our inventory for the availability of these items, or they can be purchased new directly from New Focus.

Newport / New Focus 2011 200-kHz Front-End Photoreceiver

  • Variable Low Pass Filter
  • Variable High Pass Filter
  • Variable Gain Setting
  • Range: 900-1700nm


This model features low-noise detectors, variable-gain transimpedance amplifiers, and two adjustable filters. The DC/30 setting prevents your signal from going off-scale due to DC amplitude fluctuations, without attenuating fast signals. The high-pass filter can be adjusted to eliminate residual 60-Hz noise, and the independent low-pass filter can be set to dampen noisy signals. Variable gain of up to 90 dB in 10-dB steps gives you a useful input range from 1 pW to 10 mW. Wavelength range for the Model 2011 is 900-1700 nm.

Product Family: photoreceiver, photodetector, photosource, optical to electrical, electrical to optical

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
