Variable-Gain Photoreceivers
Fast Optical Power Meters

OE-200

  • Adjustable Conversion Gain from 103 to 1011 V/W
  • Equ. Input Noise down to 10 fW/√Hz
  • Bandwidth up to 500 kHz
  • Rise Time down to 700 ns
  • Calibration Traceable to NIST Standards
  • Signal Filters
  • Manual and Remote Control

The Ultimate High-Speed Power Meter

The OE-200 Adjustable-Gain Photoreceiver is designed for a wide range of applications that require the fast measurement of low light levels. With its maximum bandwidth of 500 kHz it is ideally suited for time resolved measurements down to the sub μs-region, as fast photo detector in industrial process control and quality inspection systems and as the optical front-end for lock-in amplifier systems. The OE-200 offers many more features than usual power meters including selectable conversion gain from 103 to 1011 V/W, switchable AC/DC-coupling, and the capability of manual and opto-isolated remote control by a PC.

Exceptional Performance also in Low-Speed and Low Light Level Applications

Besides the use in high speed applications the OE-200 also shows top performance when it comes to the measurement of slow varying, continuous wave (cw) or low light level signals. The low-noise multi-stage amplifier design and the switchable 10 Hz lowpass filter allows the precise measurements of low optical powers down to the 100 fW range without the need for further averaging.

Calibration Traceable to NIST Standards

The LUCI-10 amplifier interface allows remote control of FEMTO amplifiers and photoreceivers with a remote control capability from a standard Windows PC with USB port.
