The OE-200 series of variable gain photoreceivers is designed for a variety of applications requiring 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, offering adjustable gain from 103 to 1011 V/W and 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.
The high precision and low drift of the OE-200 ensure repeatable and consistent measurements in the highest gain setting. All models with fibre optic input come with an optical calibration for reliable and accurate results. The OE-200 can also be used as a precise and fast power meter with a high bandwidth of up to 500 kHz and a wide dynamic range of up to 100 dB.
