Sensitivity Meets Versatility


The OE-200 series of variable gain photoreceivers is designed for a great variety of applications requiring the fast and precise measurement of small optical signals. By combining a low noise transimpedance amplifier with a silicon or InGaAs photodiode a broad wavelength range from 190 nm up to 1700 nm is covered. The integrated amplifier offers adjustable gain from 103 to 1011 V/W and thus allows the measurement over a wide dynamic range from ca. 100 fW up to 2 mW optical input power. Its high sensitivity is achieved by a low noise design resulting in a noise equivalent power (NEP) of minimum 10 fW/√Hz. Many additional features like switchable signal filters, an offset adjustment and the capability of manual and opto-isolated remote control by a PC make the OE-200 the most versatile photoreceiver in its class.
Wide Bandwidth for Fast Measurement Speed


In addition to its high sensitivity the OE-200 also offers a fast signal response. With its maximum bandwidth of 500 kHz it is ideally suited for time resolved measurements with a signal rise time down to 700 ns. Industrial process control, automated measurement systems and fast opto electronic control loops are just a few of the many applications that can profit from a fast optical front-end realized by the OE-200.

Fast Fiber Optic Power Meter with Calibration


The high precision and low drift of the OE-200 ensure repeatable and consistent measurements also in the highest gain setting. All models with fiber optic input come with an optical calibration for reliable and accurate results. Thus the OE-200 can be also used as precise and fast power meter with a high bandwidth of up to 500 kHz and a wide dynamic range of up to 100 dB.
